it should not be counting only the last day of the team quality. this is very unfair to those team that always on the top of the that LV~ like LV7 facing LV11....LV8 facing LV14, higher LV can always gain back their quality...while each LV has limitation of the player quality, like the LV11 has Q78 players....while in LV7...even using 1800+ token for a personal trainer, the max can go is Q74~ fair? (and i am only talking one player...1800+ tokens!!!)
this should be change to the team quality (14 or 11 top players) of the whole season...(like the average daily quality of the top 14 (or 11 players) in the team and then divided by 28), this will make a little bit fair instead of the "cheating" (last day selling and regain the quality in day 1 of the new season...)
if not, i am always have 7 stars players in my first team, and in CUP, i am always facing with very high LV team with my "same quality" (and then they gain their quality back!!)
