Depending on the part of the raid you are in Voidwalker and Stormcaller are useless as well, Sunsingers have a decent neutral game with there Nades and flamesheild. Also We all screw up from time to time and die, IF you are on your lock and die you have the ability to rez and save the wipe. Also I have in situation where a teammate who was a titan or hunter was about to die I would jump in front of them and take the hit then self res to avoid what could have been a wipe.
