Playing APU this is so far from the truth, even fully buffed you still drop like a bag of shit, and we no longer have the joy of debuff either. Clan mates tend to go on about APU's only viable for defence due to being so vulnerable.
As a WOC APU with a green/orange swirly out, I always seem to feel the full force of an attack first, so I tend to often be a UG whore to allow for my heal to catch up with the sheer damage inflicted.
