I'm not sure if you are aware, but that is quite literally the "name of the game". You need to have and stick to a solid development strategy as you build your roster. If you feel you are being forced to focus on this more, then that's actually a good thing, because it would be a rude awakening when you moved up anyway. Also at 2.8, you need 6 and 1, which is the same as you did before.
I would also suggest/caution you from upgrading anyone who doesnt fit your plan, everyone in your general area will be in the same situation and the better planned development will "win the day" in the end.
Honesty calling GAC a total fail, is probably one of the least likely things you will get support of from the player base.
