After reading more of the thread, I completely agree that gear doesn't automatically = skill, but at the same time, having good gear (myth or otherwise) doesn't automatically =/= skill either. Again, some people are just arrogant and unfriendly. I've been the same tank through out my gearing experience. I research fights that require movement and placement, I dodge AOEs, I rotate my CDs, I preload IB when I know a big hit is coming, etc. I can tell you this for certain... obtaining my relic and some myth has definitely made my skill show much more. When I first hit 50, it was hard to hold aggro and stay alive even when I did use everything properly. Now, with the added stats from the gear, I'm able to do the same things I did before and actually succeed. So again, gear may not equal skill, but it is most definitely a must if you want to perform well.

On a related note, I'm also always very nice and I've explained the same strategies to new players in dungeons each time they've asked without once being an ass about it. Honestly, to me, it's the tanks job to lead the group. If you don't want to be a good leader, pick a different class.
