Edit: after playing to 1000 coil, reading up on some other peopl's arguments i edited the post.
I don't see mutch reason on banning the pokes outside of having:
-easiest revenge kill, Kill if grabing momentum.
-slighty unhealthy against poison types, mainly skrelp, trubbish, stunky and croagunk but this would also means berry juice pokes like magnemite( or more in general sturdy juicers) would be come better.
And both bad parts come infact from diglett.
The main problems it has are in teambuilding and risky offencive play styles. I have been playing LC from the start of X and Y and have seen how the poke(diglett/It's play style) can tear apart some teams easly also pressuring stall teams into a harder zone. However, there are some pokes that can reliably deal with it and even counter act against trapping very well, especialy pokes like pumpkaboo shine with this in mind. But also pokes like Porygon can reguardless of set REVENGE DIGLETT. Sadly this is a
limited list.
I might actualy start the first argument here,
Diglett , LO diglett is the main treath people care about and that is definatly true sadly it needs rock support(exept if you want to miss out on sub and have a hard time against pawn/sucker users) and even then it still misses out on some important KO's. It has plenty of checks even ignoring scarf users like chinchou.Sadly this is LIMITED.
It's a revenge killer, nothing else. I have already posted an argument about why diglett shouldn't be listed A+ and the fact people care this mutch about the poke just make me think this is like fletchling all over again,
It is however Unhealthy limiting teambuilding.
Edit: after i played some more my self against other people with rater diglett weak teams i can see peoples argument of it being ''a bit too easy'' to work with that.
I won't say ban/not ban on this one cause i will load my self untill the right coil to say that.
Gothita is another subject, currently pursuit trappers are rare, or atleast the move it self is rare. Pawniard doesn't need it(and it checks gothita reguardless), stunky in general is rare, houndoor isn't too common but is one that could still carry it. And those were the main once.
As for what the poke can do: not mutch imo, it can check a hugh amout of diglett's weaknesses but slower bulkier pokes like spritzee,ferroseed,porygon still stand strong even if you trick the item. It would stop them from doing there bulky job but still form a slight treath.
Just 1 more thing, WHY IS THIS SUSPECTED, i can see the combo with diglett but outside of that it fails at about anything!(this again brings diglett into subject)
It's negatives in points:
-Misses out on allot of important kills even more then diglett, like foongus/skrelp/Max Hp evio mienfoo.
-Pursuit trap/ghost types are the bane of it's existance.
-Weak to priority just like diglett.
-Fails thanks to it's low sp attack power at killing important treaths and tricking the scarf doesn't always remove the treath.
-Is forced to run scarf, even tho it can trick it, it lacks in special force thanks to it and not running scarf makes you sit with the most akward speed tier of 15 what is even below pawniard's 16.
No where near ban worthy if anything this thing properly makes a good part of play for the LC meta.
No-Ban
This brings up the main question i would ask: what exactly is it that is unhealthy/punnishing?
I could already list fletch+diglett cause those apparently killer everything combined. But i would start a different one: Gothita + diglett, the combo it self is more deadly then fletch + diglett even tho that is a very well known team demolishing combo. It's no douth some U-turn + 2 trappers + pawniard makes up the biggest part of the top ladder but there will always be better teams reguardless ,heck, see mienfoo's useage the beast is solid on almost every team but not broke in any way.
Maby i Was asking the
wrong question, maby i shouldn't look defencively teambuilding but if you play agaisnt it!
In this case, the trapping teams actualy have an easier time against most current teams/play styles. Hyper offencive (could)/Bulky offencive/Trapping(it self) teams seem to be the most usefull answere against them.
Other play style that have a hard time:
-Ballenced, ballenced teams need to take hugh risks to stand stable against this play style, however it doesn't mean they couldn't work.
-Stall, in an all around meta game, stall even tho it's hated by allot of people is demolished by trapping if trapping is done right. Teambuilding stall teams in the current meta is hard, but also not impossible. However this
limits allot of options.
What if trapping became banned?
That is rater an interesting question. All i can say however:
RIP to skrelp, like actualy Skrelp can get a free kill agaist almost anything it's astronomical special attack can break trough most thigns.
If Gothita/Diglett become banned i will most definatly vote for skrelp to go A+. It's not that trapping is needed to keep skrelp from being OP, but it most definatly drag's it's viability down.
As for other already listed pokes:
-Trubbish would become more viable.(B/B+ viable imo)
-Stunky can rise higher again(B+).
-Tentacool........
-
Croagunk will be a monster again. (A-/A)
-
Abra: might sound odd, but knowing LO abra is the main thing that is powerfull and usefull knowing it now only has to worry about pursuit/sucker users.
-Chinchou/Ponyta/Magnemite will also be allot more free.
-
Pawniard is even bigger then before, what is worry able, but no where suspect
-Trappinch... YES, this isn't a joke this thing won't be outclassed by Diglett anymore and will be able to deal with some treaths, sadly it's rediculess lack of speed makes it nearly un-useable for reveng killing(TR maby? reguardless it would rise but not become a viable enough replacement for diglett.).
-Magnemite will be mutch more used yes, more viable also but still A+ imo.
As play styles:
-Trapping as a play style depending on the ban will be nearly not existant.(exept if you want to run pursuit trapping + trappinch in that case go wild!
-Ballenced will be hugh, like even bigger then before HUGH.
-Stall will be more viable( i am a stall boy my self so i wouldn't mind it ;p)
Overall the post i made was to point out multiple clear points others could focus on.
