Well, like I said earlier, neither of us are in the habit of using Iron/Stone-pots. We've never used them, on any progression fight. I'm not debating, or questioning, their usefulness.
But considering if he and I *had* used them, I feel the healers' "results" would have been the same. So, it seems a lose/lose situation for me.
A similar thing happened with me tanking Kael (when he was still progression for us). We had 3 attempts where I was going to tank him. First 2 attempts, we never even got *to* Kael. 3rd attempt, I (admittedly) mess-up once with avoiding Pyro. I get called down from tanking, and the try after, we win.

Granted my failure caused that one, and now I'm just rambling about my frustrations w/ Pally-tanking (a whole other issue).
So...this might seem a bit n00bish of me, but what is WWS? And where can I get it? I've heard/read about it before, but to my knowledge, no one uses it in my guild (we're a very lax raiding guild; on a server that had 3 guilds break into BT/MH only weeks before 2.4 patch [my guild included]). Perhaps, if I have another shot at other bosses, I can illustrate to them the actual damage differences between me and the Warrior. So far, I've only been able to convince them at me tanking Leothoras and RoS-P3 on a regular basis.
(Oh, I'm sorry if this overall post de-railed the main topic, so...yeah.)
