much of homeslice's post is completely incoherent, but i will attempt to dissect it anyway. my points will specifically be about the two typings suggested, fight/grass and fight/elec
Fighting-
I have some extreme reservations about this type. You could argue for days about how Fighting is the best type behind Dragon, if not the best type.While it may have some potential towards rain teams because of an SR resistance, I still generally don't like the idea of using a Fighting type to stop common types, seeing as it is one of them.
Fighting is the seventh most common type in OU, behind water, dragon, steel, ground, psychic, and flying. Three of the OU Fighters, Conkeldurr, Toxicroak, and Lucario, are hanging on by their fingernails. This leaves three good OU Fight Types in Keldeo, Breloom, and Terrakion. Frankly i'm not entirely sure why it was listed in the concept. w/e
It's like a lesser version of the Dragon situation, but most fighting types hit so hard with STAB moves that other Fighting types not named Gallade, Toxicroak, or Heracross can't reliably come in on without being threatened to get 1-2HKO'd.
let me get this straight. you are arguing that strong STAB moves which dissuade frail pokemon with neutral typings from coming in is a /weakness/ of the fighting type? or is this lumped in with the previous quote, in which case ^
And honestly, the only thing you're getting out of a fighting type besides an SR weakness
and a tyranitar pivot, and a Heatran counter, and a threat to rain
is the ability to stop Ferrothorn and Hydreigon only if it is for some reason chosen over Lati@s. Other than that, you're destroyed by STAB Psychic moves Lati@s might have,
you can't win em all. on the bright side, you can volt-switch out when lati@s comes in to whichever pokemon is appropriate for the situation. worth noting that the only truly threatening lati set—subcm—doesn't run psychic moves
most likely crippled by a Scald to the face from Politoed or whatever Bulky Water they're probably running,
i find it amusing that despite the presence of two strong special fighting moves (aura sphere and focus blast) you polljump to the assumption that this CAP will necessarily be physical if it is fighting type, and use it as an argument against the type. Furthermore i am amused by the fact that you support Elec/Dark, a typing that is getting so much traction largely for its ability to pursuit trap bulky waters—an ability that is completely neutered by a scald burn.
and really only have something going for you if you're grass typed also, which again will be talked about later.
let's talk about that now. you are convinced that it's either cap5 or venusaur unless cap5 is the god of all things support. need i remind you that many successful sand teams run both landorus and gliscor—which have the exact same typing. Both terrakion and tyranitar are Rock typed. Lots of rain teams use Tenta, Keldeo, AND toed, also Ferro AND Rachi. Just because two pokemon share the same type doesn't mean they have the same role. Venusaur is a sweeper, Grass/Fight is a defensive pivot and rain counter.
I could MAYBE deal with dragons only because they usually get great coverage
this deserves its own response. "traditionally, dragons do x and fights dont" is a completely flavor argument that has no place in a competitive discussion like this.
and resist Water and Electric, but Fighting doesn't do that.
Fighting/Grass does. Fighting/Elec resists half of that. Sun provides a water resistance.
Fighting does have the Rock resistance for Stone Edge from Sandstorm teams, but it doesn't resist Ground anyways and once again is really relying on it's dual typing to give it some backbone.
I find it amusing that "a neutral switch-in is no switch-in at all" is your argument here, and yet you support electric/dark, which is a neutral switch in on almost all of the pokemon it is intended to beat (latios, latias, politoed)
