Good post! Great ideas! I like everything you said and i would really like to see the devs make a comment about the changes you have suggested.
Blizzard usually doesnt make drastic changes midway through an expansion just as you say but is swapping the talents from different tiers the way you suggest really that drastic? (Im asking)
I just want to mention something about rogues finishers costing both energy and combo points that i read here somewhere while as monks and ferals dont have the same system. That in itself could be the "overall dps increase" that alot of people are yearning for. Although it might be unbalanced, havent given it a lot of thought.
