I really think most people aren't voting on any legitimate basis for Fighting, other than the fact that Fighting itself is a great STAB option and it may make a cooler Pokemon. That's pretty flawed reasoning from where I stand, as it doesn't necessarily mean it's a great partner for Togekiss.
You do realise, this is the same reason why a lot of people are voting for Ground as well, and why the two types we have ended up with here
both happen to have good STABS, and
both happen to have horrendous synergy with Togekiss.
Both sides are trash talking so much, thinking up excuses for why theirs should be the type of choice, when, in truth, both types are only here because, as per usual in CAP, they're good STABs.
Why are people voting Fighting?
So bulky waters, you know, the ones all over the Metagame, don't destroy the core.
Vaporeon: Walks all over this. Ground CAP11 can't touch it, and it can beat Togekiss with Surf-> Ice Beam or outstall with Toxic.
Swampert: Assumeing the mixed set, Waterfall -> Ice Beam, Togekiss will be KO'ed if it switches in and rocks are down. Neither can do much, except Togekiss flinchaxing.
Gyarados: Switches in on CAP11, threatens Waterfall, may get a free DD. Oh, and Gyarados tends to carry STONE EDGE as well, so Togekiss won't live either.
Suicune: See Gyarados, but replace DD with Calm Mind, and Stone Edge with Ice Beam.
A Ground-typed CAP11 is just set-up bait for Suicune and Gyarados, and Togekiss can't do anything against them either. This is why I voed Fighting.
Ground types are also utterly useless against Gengar, Rotom-A and Zapdos. At least Fighting-types can hit Zapdos.
Both types are bad for the concept.
Both types are only here because people can't think past STAB. If people were actually thinking of synergy with Togekiss, then
Steel would have won by a landslide in the first poll, because it is easily FAR better than Ground and Fighting are for Togekiss.
I've already given evidence as to why a core with CAP11 as offense, and Togekiss as support would be doomed to failure, due to Togekiss being outclassed, which only leaves duel-offense, as Fighting and Ground fail at support. Which then means Rotom/Zapdos/Genger/Bulky Waters walk all over it, based on the type chosen.
That's the last post I'm probobly going to be making, possibly in the whole of this CAP, dependant on if anything that might save this concept comes up. Or if I need to bash some heads together to stop people posting false rubbish.
