Unless TFB is tuned before live, its taken about 6 hours of progression for 4/5 HM TFB.
Is BioWare going to be churning out content when it's F2P or are we stuck with super easy content?
How do I put this nicely.
The average raider will probably take 2 months to get this clear. Ie the majority of subs,The average player will probably never clear it on HM till it A) gets nerfed B) is irrelevant content.
You churning through content a lot faster than bioware can create it is your problem. Yes it might not be super dooper ragnaros/Sinestra/HM LK hard, but it's not that sorta game.
