When I'm out with heroes. No rez on the monk heroes, they got mesmer interrupts for E management. This leaves rez skills on all the other heroes, usually 2 rez signets, a mesmer with Rez Chant with a necro with Flesh of My Flesh or a paragon with Sig of Return. My character, I decide on a rez by area demands.
The real problem is with player groups, guildies or pugs. The idea of dropping the rez for another skill is an epidemic.
A recent Eldritch Ettin run cemented my thoughts on this. One UA, no prots, no debuffs, and one pissed off ogre that hits for 600+ dmg. Three wipes and a lot of running and hiding behind SoS spirits. Once the monks went down, which was 10 seconds into most fights it was a wipe waiting to happen.
