Not a problem. Something I forgot though is that there is a weekly cap on how much you earn, and that will be increased as the xpac continues. The collecting of that cap per week is still high enough that a lot of people are upset and calling this an alt unfriendly xpac as they will not be able to maintain alts as easily as a main character. I myself usually maintain about 5 at an ilvl just over LFR difficulty and will probably only be doing 1 depending on how the acquisition of AP goes. When you take into account the amount you need for 1 point in the artifact and add 2 specs, if you want to maintain all 3, there is a lot of work going into 1 character in Legion. No pros or cons to that arguement yet as we'll have to wait and see how things go and are adjusted.
While I agree that they can expand on flight based gameplay, I still think it would be pretty hard for an MMORPG to do so without making part of the game a flight sim or taking the things people dislike from the ground and putting it in the air. For the last few xpacs it has been unnecessary to play the game to its full potential, but I've never been against it being in the game, and would like to see Blizzard be able to do something to make everyone happy. I just have no idea what that would be.
