lvl 1 dk and bd has 648 hp
lvl 1 pala has 589, that's -59 for pala.
Then try to lvl them up to 2, 3 or 4, if pala gets lesser extra hp on each lvl I'm pretty sure you will answer this question ;)
1st: tanks gets more extra HP in each lvl than rogues, druids & .....
2nd: some class have 5 or 4 percent extra hp on bonus skill, Im too lazy to check it ( it's barb I guess )
3rd: Depends on equipments and enchants.
Those 5 ppl who voted debuffer are dumb. That +10 homo does not have skills, he doesnt even know how to land his circle on his opponent. That homo should be on MOST HIGH amp section poll not BEST.
