Afterlife is bad in m+, period. Censure is the much better option due to granting the healer an opportunity to stun a mob for 5s (provided no DR), during which time no one is taking damage from that mob. There is no situation in m+ where 7.5 extra seconds on an ability that requires you to die to use it, is preferable to an on-demand stun.
I don't think OP was upset that the druid healer didn't pull X amount of DPS. He was upset that he used 0 globals to contribute to the group's dps. It's hard to believe that in the entire run, there was no downtime to cast even 1 Sunfire. Given that OP saw 0 dmg done over the duration, he probably concluded that the druid was lazy but came to MMO-C to get a consensus. Of which, most good players agree with him.
