I have updated the Jaraxxus tactics page with an updated Step by Step Tactics section, stay tuned for a fully narrated tactics tutorial movie.
Blizz issued a clarification on their forums that Icecrown will not have 34 bosses.
I put in the Yogg achievement with what I hoped was a ridiculous stand-in number. Clearly it wasn't ridiculous enough because players were variously excited or worried that it was a real number.
Then in an example on how we don't want raids to rotate in tanks, I wanted to pick what I hoped was a ridiculous number so that players wouldn't try and and deduce from my answer how many bosses Icecrown has.
Sadly, my sarcasm doesn't translate well to the forums.
I just updated the Northrend Beasts Strategy page with a full step by step tactics section. Stay tuned for a fully narrated video guide of the encounter.
On a different note, blizz post on their forums implies that the upcoming raid instance Icecrown Citadel will have as much as 34 bosses (!!)
I don't know that I would say we want tanking niches. I ultimately am agreeing with what you're saying, but once we say "tanking niches" players have visions of the DK who parks outside of Icecrown until boss 4, 17 and 31 (yes, IC is that big)
Now that the crusader coliseum is being tested heavily in PTR we keep updating the Coliseum Tactics page. Pay special attention to the valkyrs tactics page as well as the jaraxxus tactics page for boss tactics and strategy.
I just finished the mimiron tactics tutorial video, fully narrated, and updated it into to mimiron tactics page
