I will look what season 7 brings but im already playing MWO, i don't have high hopes that i will stay here much longer. I have 2 accounts, 13 VA/LG's and what you said, No more dil/fleet-marks will make this game a grind, much more than a job and i play for fun.
I'll drop into the forums occasionally to check on the state of the game. If it ever becomes less of a grind I might give it another shot because I love the IP.
Last time I got burnt out from the grind because I was doing the Neutral Zone + Defera dailies on 4 toons. I toned it down to 2 toons but it was just so unchallenging and repetitive that I stopped completely. Moved over to STFs but got bored. Maybe a 2 season break will build up enough content for the game to feel fresh again.
