You are reversing the roles essentially. Tanks are a tank for a reason. They are not healers. Tanks getting abilities that not only step on healers' toes but also allow them to help shield and heal allies is the absurdity icing to this cake. You cannot have it all. Your dps will be reduced to 25%-45% of a healer if you want to have this type of healing power. What should the healers do? Have you not seen the one healer trial runs on extreme going on right now and see how 1-2 minutes of the entire fight the scholar had to heal with the rest o the time spamming broil? Is this where we are going? Officially reducing the number of healers to 1 and eventually going to 1 tank and 1 healer for every static group because that is quickly becoming the meta for healers at least. I can see it even happening with the minimal gear.
