When I last raided I kept 3 of the self heals loaded and often was the last alive. A dead paladin is worse than almost any other class due to the utility they can provide or the raid saving abilities. I remember doing sisters in underfoot and we were down to the last sister and it was almost dead and we wiped save me and I kept myself alive long enough for a cleric to get back and then a full rez to the raid and a Zerg till it was dead. I can see not loading all 3 these days but the value over burst is evident. That said old habits are hard to break and even if I have the self heals loaded I keep burst up.
