DPS Sorcs or Heal Sorcs?
I find it hard to imagine any heal spec being effective with maxxed endurance. Well, dps too for that matter. Heck, as a healing sage, the increase on my free self heal (with high willpower) outweighs the hp increase (with high endurance), let alone the increase of my other heals.
Seems wrong to me.
I don't know what his skill tree looks like, but he's famous on our server and difficult to kill - a sorc with almost 22k hp in pvp gear.
Havent tried pumping Endurance myself, but i must state that it seems viable.
