There is absolutely no reason to have 30k health in the game at this current stage. All you are doing is making it harder for your healers to top you off. You are better off having the defensive stats period.
No matter how much def and shield you try to stack, you will take full-hit attacks and you will take them several times in a row, it's good to have a hp buffer for those times. Running around with 22k (as mentioned previously) makes you just annoying to heal, hell most 61 geared dps/healers have ~21k hp.
