Haven't been the biggest CG fan but there is an argument to be made about making something exclusive for those willing to pay money.
If you are f2p...you are not likely going to be affect one way or another. The number of Revans will be small and restricted to the top of the arena food chain (like top 10 to 20). If you are not there...it doesn't really make sense to push for Revan.
If you are, you have to factor in the costs of losing out on crystals/refreshes.
