When did I ever say take away his bow? Quit making shit up and start making actual arguments that aren't based on stupid premises. You don't need a cast time. Nobody said that. But if you're on the move, you shouldn't be doing 100% of your damage while EVERY other class suffers from the same mechanics. Besides, aside from your three songs, you're really just a beefed up archer.
It's quite obvious this is your first MMO (welcome) if you don't think a nerf is coming. Classes that are too powerful get nerfed, classes that are bottom tier get buffs. It's the cycle of an MMO that occurs as an attempt to balance the game. ARR is no exception to this, not if it expects to have a long life.
