I read that Shadow Tanks are quite difficult to heal in Hard Mode.
Is this true ?
unless they are very VERY good at juggling cooldowns, then they are fine. but of all three tank archetypes, they are the ones that give me the biggest pause when I don't know them and just get them as a pug, because in personal experience, they are the hardest to play well, because of being so dependant on active cooldowns.
that said, skilled shadow is magical. I healed an assassin through 50 hardmode while leveling back when 2.0 just dropped and dude was in lvl 45 blues. I thought I was toast. and then he proceeded to be one of the best, easiest tanks outside of my guild that I've healed so far.
