way to tip-toe around the answer to your own question: self-res breaks encounters because it bypasses wipe mechanics meant to kill the whole team and restart the encounter. sure, titan bubble can RESIST wipe mechanics by enduring their otherwise overwhelming damage, but it cant do it quite like self-res can, hence titans not being able to solo Atheon nor Aksis. I have MANY arguments, but your just CHOOSING to ignore them. theres also the fact that bungie themselves have said what i have said here too! i never said that res-locks can EXCLUSIVELY solo raids, i said that they are the class that has solo'd the most raid encounters, as well as having exclusively solo'd certain encounters, like Atheon and Aksis, mostly because i was vaguely aware of another class doing Oryx, and also because CE is solo-able by all classes, so i had to choose my words carefully, unlike you and your repeated and proven lies. and then there was the whole thinking i was talking about PVP, when i never mentioned it.

The self rez was meant to prevent wipes. You seem to be so utterly clueless that you are claiming an ability made to stave off a wipe is bad because it "voids a wipe mechanic", that is so utterly stupid that you should be ashamed to post. You do realize that damage is a game mechanic, right? You seem to be so dumb you cannot realize that Ward of Dawn void's a game mechanic as it is ensuring that the player avoids all damage by being in the bubble. So far its pretty clear you are just going to pretend like wipe mechanics are immutable and that some how a self rez is game breaking, when the proof is to the contrary, but what do I expect, you are like the morons in WoW that try to argue Battle Red is game breaking because it allows a resurrection wjile in combat.
