Plo Koon's basic not debuffing properly
Hi, I know this belongs in feedback, but there's no traffic there. I'm wondering if anybody is having the same issue? Plo is supposed to remove a random buff, but often as not he doesn't remove any. Buff removal is his only redeeming quality for my team. Please fix his basic to fit description

To me the problem started occurring when I maxed it out.
What everyone assumes it should be....
"Remove one buff AND 50% chance to remove all buffs"
What it actually appears to be....
"Remove one buff OR 50% chance to remove all buffs"
So what I see happening is I fail the 50% chance and get nothing instead of having it fall back to the one buff removal.

Problem is that it is worded like the first and not the second. It's extremely annoying and I wish they would clarify if this is intended or a bug.
That was most definitely changed a while back. Buff removal is not tied to potency any more. It should never be resisted. I remember when they made that change, because I used to use Yoda tenacity up to prevent my taunts from being dispelled. As long as the target doesn't dodge, then dispel should work 100% of the time.
And to the OP's original question, yes. I see the same bug. Don't use PK too much as he still isn't very good. But on the rare occasion he fills in for me in GW his dispel still works sporadically.
That's different tho, inflicting a debuff is tied to potency. You need to boost her potency up to land it more often.
Ability block is a debuff. Debuffs can be resisted. There are a small number of exceptions. (Mace's expose for instance) But it will say in the description that it cannot be resisted. All other debuffs can be resisted unless the description specifically says that it can't. Dispel is not a debuff (red negative effect over the head). It is the removal of positive effects, and cannot be resisted.
