Don't forget that ferrothorn's 4x fire weakness is halved in the rain, where he is also a staple. I think ferrothorn is too strong defensively to stay in OU. With proper defense investment, he can survive a 252 atk jolly scarfed terakion CC if itnis at full health, and cripple it with twave or ko with power whip. In my book, this is just too good for OU.
And I assume you're to be the first of the many bandwagoning on Ferrothorn now that statistics are out and a few notable players have mentioned an opinion.
It'd be nice if we ever got to a point where people didn't feel the need to look for
something to complain about.
Ferrothorn isn't suspect because it isn't broken. It's incredibly good at what it does, but you aren't required to use it in order to win.
I think we've been a little quick to dismiss Ferrothorn, probably due to our inclination to focus on offensive Pokemon when it comes to nominating suspects. I'm not saying I believe him to be a suspect...I'm on the fence tbh and as such I'd like to see a little more discussion on him than 'lol x4 fire weak.' Anything's better than yet more weather discussion, right?
Aside from being 4x weak to Fire:
• Weak to Fighting, common type
• Taunt
• Trick
• Magic Bounce
• Easy to set up on with particular threats; Volcarona, Heatran, Dragonite, Garchomp, et cetera
One could argue that Ferrothorn has a bigger overall impact on the metagame than weather because, thanks to his ridiculously good typing and stats, he can reliably and consistently set up Stealth Rock and Spikes. Such easy and convenient access to those hazards totally changes the flow of the game. It becomes too easy for something like Specs Latios, Landlos or [Water type in Drizzle] to just unleash their powerful attacks knowing that not much can survive after accounting for the entry hazard damage. The problem is only made worse by the fact that Ferrothorn is so darn good and the Rapid Spinners are just plain awful with the exception of Starmie who usually doesn't bother spinning anyway.
I'm reminded of a situation in 4th Gen UU where the combination of Froslass + Moltres was believed to be broken due to Moltres being able to 2HKO almost everything after Froslass had laid down Spikes. So what did our voters decide? We banned Froslass. I think we're in a similar situation now - players have incredibly easy and reliable access to Spikes and can compliment it with some ridiculously hard hitting Pokemon like those mentioned in the previous paragraph.
It's no coincidence that 6 of the top 10 most used Pokemon are immune to Spikes when using their standard sets.
I'm sure there are plenty of reasons to disagree with my reasoning but don't bother with 'other pokemon learn spikes too!' because there hasn't been such a capable user of the move since 3rd Gen Skarm (and you couldn't pair him up with fucking Choice Specs Latios Draco Meteor spam). A lot of Spikers are dead-weight outside of their primary role but Ferrothorn is capable of so much more thanks to his high BP attacks, Iron Barbs (seriously, talk about overkill) and Leech Seed.
tl;dr: Ferrothorn makes it way too easy to get up entry hazards, lack of viable Spinners makes it really difficult to get rid of them and there are too many powerful attackers to take advantage of the spike stacking. It could well end up that by banning Ferrothorn we avoid having to ban Latios, Thundurus, Garchomp etc.
Sure I'm gonna be quite unpopular for this but go ahead and tell me what you think anyway. ^_~
This idea that Ferrothorn has an detrimental impact to the metagame due to its ability to set up SR or Spikes easily thus allowing top threats to sweep with ease is two fold, because its Ferrothorn that is keeping a lot of these dominant threats in check. As Jibaku pointed out, Ferrothorn is a glue that holds many teams together because it is effective. If you take out Ferrothron, honestly, you'd likely making the problem worse. While setting up hazards could arguably be more difficult by removing Ferrothorn from the picture, the fact is that we don't really have a shortage of good Pokemon who are capable of doing the job. Forretress, Deoxys-S and Deoxys-D, Skarmory, and Roserade are all capable. Less seen alternatives are Crustle, Accelgor and Scolipede; Crustle has access to both Stealth Rock and Spikes + Sturdy, while Accelgor and Scolipede have high speed, with Scolipede having access to Toxic Spikes.
If you were to nominate and subsequently ban Ferrothorn, all that would really likely happen is it would be replaced by something that is still capable of setting up hazards (like one of the Pokemon I mentioned) and we'd have one less defensive threat to check those Specs Latios Draco Meteors your talking about.
