@kaisinel, Your sentiment is correct, but your attitude is horrible and annoying. You can't just say with that "clear content, then talk to me" attitude. It sucks and doesn't bring much to the table.
Not all healers are comfortable with tanks running full slaying and you have to acknowledge it.
People seem to have the misconception of the whole STR/VIT idea. The only reason why STR is way preferred nowadays is just because tanks in general realize that they don't even need that much HP to survive. Great tanks know how much fluff damage they can take without CDs and how many CDs they need to tank tankbusters and KNOWING when those CDs will come up again for the next sets of tankbusters. I personally use mostly STR accs to a great success. But that doesn't take away the fact that the huge challenge is to MAXIMIZE your potential WHILE staying alive. That comes back to what healers you are with and not how you have always played. They are not the same, nor ever will be.
