^ not worth a response. If you get that butthurt and trollhardy over an OP like that, please stop playing.
Generally if it's the first time in a dungeon, i'll say "My first time, tell me what I need to know", then start pulling once the buffs are out. Trash is trash and the routine is pretty much always the same. My second time, I usually just toss out "It's been a while, just let me know if I mess something up." and pull once buffs are out.
Don't sit around and wait for explanations if you've done your proper overview research of the dungeon/bosses (which is a good idea), most tanking is just a matter of routine (collect mobs, maintain threat, maintain overwatch, wait for DPS). Players like "the guy above me" can just rot in a queue, as they aren't doing anyone but themselves favors.
