Striker bossing combo and question

Barrage -> 2xFF/drain -> barrage is better than barrage -> CSB -> barrage which is better than barrage -> CSB -> drain/FF. The last one you have no reason to be doing since barr -> CSB works flawlessly.

Of course SE benefits barr more.

Pap sucks for buccs. No controllable stance means you can't be on the top because he'll knock you off every time and being on the bottom sucks because he'll dispell/stun you all the time.
