I'm just ignoring the PTR stuff at this point.
The first thing they said about rogues was that they're going to get rid of Agonizing Poison (the key talent of the best performing spec) - since then they've posted no changes to that spec except for an energy cost increase to a talent that competes with AP.
Then they post some promising changes to Subtlety...and roll them back two weeks later.
Who knows how it's going to end up. If it's not coming until mid-late June, it's not worth worrying about until it's further along.
Also - got the bis rogue shoulders last night as my 9th legendary. Theyre fantastic. The legendary system is working just fine guys.
