I have to agree here on almost everything. I like CoH upkeep/resource system more. Commanders are just dull to me and I prefer dual tree doctrines that are actually real strategic choices. I hate all gimmick stuff like fire-up you mentioned.
I would never pay 9 bucks for a DLC doctrine though. DLCs should focus on cosmetics only. Period. Buying champions in League of Legends is annoying but acceptable because LoL is f2p game not full retail AAA title as CoH2. There is even better example how free to play model can let people stay competetive. Dota2 my friend. You pay only for skins, all heroes are avalible to everyone for free, heck, users create content to this game and earn money from it.
To sumarize, I think that not much can be done to this game at this point. They will not change core mechanics etc. We will probably see more content like new commanders, ToW missions and probably soon new expansion with 1 or 2 factions with extremely expolitable mechanics that everyone will rage for months
My only hope for this game is huge mode that will bring vCoH mechanic/factions to this game. By I hope Relic will decide to prove me wrong.
