Im fine with those things becoming important for the endgame raid type content. I just dont think they enhance the game when it comes to the instance runs people do daily. And i definitely dont think it enhances the gameplay while youre low level.
Perhaps not, but you learn to play your specc and i emagine that this is a huge benefit for some players. I think that learning to play you role, and doing so in flashpoints is fun, and is great for prepairing you for the endgame content. This could be a way to ensure that when players reach endgame content they are ready to do their part and know how to do it.
There is nothing more frustating than grouping with a useless tank/healer that causes wipes.
