Cause the discussion is not on the 70's section, but in general
and it's easier for people to keep track.
Not really, sifting through that thread for relevant 70s info is a pain in the ass. Each bracket is different, and the things that have to do with twinking @ 70 in MoP won't have anything to do with twinking at other brackets.
For instance, the item squish (if it happens) will affect 70s while leaving everything ~60 unaffected. It will reduce the overall HP pools and stats of all players @ 70. In turn the scaling of abilities, enchants, gear, and gems will be lowered too.
It will also affect the effectiveness of cata tinkers for level 70s - they won't be nearly as powerful.
Resilience as a base stat will change how resilience is budgeted @ 70 between gear and gems.
The addition of a new class will pose interesting questions about balance.
Talents and abilities themselves will change for everyone, but @ level 70 there will be questions on how viable the new talent system is. Will players level to level 75 to get that talent, thus exiting the bracket? Or will they stay @ 70-74 and sit on the level 60 talent? What abilities do they stand to gain/lose with that choice?
Ect, ect, ect. These are all questions that have to do with the 70 bracket and will have unique answers for the 70 bracket. We shouldn't be mixing that in with the existing thread.
