Question About Tanking in Dungeons
I've been playing for about five years now, and I've usually always leveled solo. Up until recently, I've skipped dungeons altogether, and leveled my main (and more alts than I care to count) through questing, dailies, world events, etc. This weekend, I'll be getting my Belf Prot Warrior main to 90 (yay!), and after that's done, I was considering leveling another Forsaken baby Prot Warrior. I really don't want to do all the quests again (although I'll do some; I do like certain areas), so I was thinking of leveling him mostly through dungeons.
My problem is, I'm very familiar with the Prot Warrior as a class, but I'm not familiar with some of the dungeons themselves. I've run many of them solo (up to Outlands) on my higher-level main, but I know that one-shotting mobs and bosses is not the same as actually doing each dungeon at-level when you're a lowbie.
I know that tanks are supposed to lead, and know each dungeon layout, each boss, strategies, etc.
My question is, how does a dungeon noob-tank get that experience in the first place (particularly if they don't have a higher-level alt to explore first)? I've run a few dungeons on my healer, but only to level 25, so I know I can get through those. It's the ones after that I'm concerned about. I can get the layout by running through on my 90, but as I've said, it still won't be the same.
I know a lot of groups I've ended up with in the Dungeon Finder (on my healer) had no patience for anyone who didn't know exactly what they were doing. It was all 'go go go, now now now, don't stop to think'. I also know that we all have to start somewhere.
Does anyone have any suggestions? Are there any resources out there I could refer to (I've checked mapsfortanks.com, but it hasn't been updated in some time, and the highest-level dungeon is BRD)? Is there anything other than YouTube?
Thanks for any help!
