This game is one of the more enjoyable games that have recently been released. What it lacks is any “game-extending” features. Once you’ve made it to REACT Progression 31 and all 19 operators to level 10 there’s not much to really keep you going in terms of progression.
Suggestion would be to develop some form of “Prestige” function whether it be resetting Operator rank, REACT progression rank, or both and associate an incentive (i.e. the rank symbol, uniform, headgear, and weapon skin).
This feature should also be totally optional as it doesn’t appeal to all players but it does allow consistent players to keep that “grind” going while waiting for more content to drop.
