i would say sk,karma,dende,poko,ulti. unless u got a ulti who stays outside to buff for short runs then u can add a turtle or something. karma are needed for same reason as poko they have speed buff.
speed didn't ruin pve it brought it back to life,gave a new aspect to the game. Mostly the reason your complaining is that your a fighter that can only do it if it's got op gear. And yes thats probably annoying but that's what it is. Before speed karma's and poko's were useless in pve just like fighters are now.
well he does have op gear that's 1 and 2 there more referring to the lack of skill it takes to complete with a speed party over a normal party where a good strategy is crucial
