Well, I mean... shouldn't that kind of be the case anyways? It's called slaying for a reason. It helps you kill better. The difference here is that instead of it boosting you to pretty much be on par with a DPS, it gives you a "slight" edge on your strength at the cost of hp.
Except, now, instead of it being, "hey! get 500 more DPS by putting all STR gear! We don't need that extra HP!" it's become, "hey! You can get like, 50 more DPS by putting on all STR gear and lose out on thousands of hp in the process."
You know... kind of like what a tank role should be. Yes, it was cool that tanks could really dish out the damage, but I have seen a LOT of people telling tanks that they should be "DPS'ing in attack stance" and calling those in tank stance noobs... Once again, to be able to maximize your role is one thing...
