Idk why but it kind of seems like if you have self heal moves, it still goes toward the healing part of the sscoreboard. Literally even if you don't heal any of your allies lol it still ranks you as a healer on the scoreboard wtheck! xD
I heard that an OP Devotion Paladin has the best "Raw" heals for endgame (I have one right now) I never ran a DC before but when I run dungeons with them I always come in 1st for heals (the DC isn't really far behind in heals, just not were I'm at lol). I'm a hybrid DPs/Healedin aha 1-70 is a joke for leveling btw
