Backstory: Last night I went into regular Nexus with my 72 warrior, along with a few level 80 guildies. They definitely tested me on keeping threat. I had some problems here and there, but overall, I managed to keep all mobs onto myself. (Though I'm quite certain that one or two of the dps held back a little to allow me time to get threat, which I do appreciate).
I was quite proud of myself for the most part though. I've always been a bit iffy on tanking, worried that I'd wipe the group, that they'd think I was a noob, etc. This is only my second time tanking a Northrend instance, and it was fun.
Being a warrior is definitely giving my shaman a run for her money. All in all, I'd like to thank all of you warriors out there for the information on these boards, and advice given. Although, I'm still learning, and far from being the best, I have a feeling that I'll get there in no time. Thanks again!
I better get a move on with leveling her to 80 now =)
