Think about the upcoming PVP and that the most common chars used are warriors almost full ATK damage. I think its better to boost the DEF of mages anyway, but as i say in the main post in the end you take your decision, but i like to balance the stats as much as posible, and in many cases the health bonus is just 1000 points more or less.
The post is the easy build way or a start to tweak yourself
