I don't think this is what we asked for. Yes this change eliminates the random factor but to what end? Everyone who gets to 50 from now on is stuck with centurion gear until rank 60 with a small chance of champion items which if their luck is as good as mine it will probably mean multiple tokens for the same item.
What about all those that have used the the pre 1.1.2 bags and have full champ gear? How a new lvl 50 competes with them with the huge difference there is between armor sets atm? Centurion gear is sub par to even crafted gear and only expertise is worth it.
The most reasonable way to go about it, it would be to have centurion bags for ranks 40-50, champion bags for 50-60 and battlemaster bags for 60+, each with the respective commendations in it and very small chance of an actual piece.
Since the current system is around for some time now and I imagine the QQ if suddenly people couldnt use their armor, champion bags should contain a small number of champion commendations along with a higher number of centurion commendations.
