I vote for raising the cap on the mega servers so they are enormous. Probably something they are going to consider if the game keeps growing with f2p
They will most likely have to do that. I know with STO, they created separate servers for the F2P players, but that would be a bit too hard to implement since what's been done is already done. I believe the only other option they have at this point is to further increase the stability of their servers (due to people noticing ability delay in the power trays...which is an indication of server overload) and increase the max server load.
