The scoring system makes most activities not fun. Having to focus on getting an arbitrary score(not very clear to begin with) instead of just having fun in the activity has completely soured my enjoyment of fire team and solo activities. Also forget trying to play with new players/friends. All you do is hurt their gameplay experience trying to help them. Another huge issue i havent seen mentioned is how screwed you are if you didnt buy the season pass(15% bonus) or wear all new gear. If you dont do one or both of those things getting an A is extremely tedious. Constantly increasing your power level just to be perpetually 20-40 levels below the combatants feels terrible. Only reason to increase power past a certain point(player power wise) is to get t4 and t5 drops.
