There's several threads all over the internet about this but I just had a couple more specific questions and value the input of alla's members.
1) On specific fights such as OS+3 10 man, how much avoidance is ok to sacrifice via gems and enchants in order to completely buff stamina (health) as high as possible?
2) On non-specific fights is the same aforementioned stamina set going to be adequate for tanking in heroic raids or will it be too burdening for the healers?
3) Is it possible to have 2 sets of the same T7.5 gemmed and enchanted differently? And should I be looking into this to be able to fulfil 1) and 2) ?
As it stands right now I am just over 34k health by myself in Bear form, 44k raid buffed with 40% dodge and 35k armor (69% reduction) -- I'm working up my jewelcrafting so I can get 3 dragon's eye prismatic gems as well as the 62 Stam +2 sockets +300 dodge on use trinket for even higher hp values. I figure with some luck in the following weeks of 25 naxx I can put myself at about 38k health by myself and close to 50k hp buffed.
Is that enough or too much and where's the cutoff?
