Guild Wars 2

…sorry, what? CC by Turrets without APT doesn’t – oh, it triggers stacks of Defiant? Gonna put my money on ‘the devs just have the thing checking against a list of damage/effect sources,’ and thus ’it’s not intentional, but they’re not likely to fix it.’

see it as bonus:
since you know how it behaves, you have up to 4 stacks of defiance that you can get rid off without knocking other mobs around at all.

sounds like one of the win/win engi-bugs to me, if treated right.

I haven’t noticed this… usually any CC is from Big Ol’ Bomb in the mightstacking phase.
