Fun & nice mechanics guarded by paywalls or ads. For Free to play player it becomes extremely ad-grindy just to be able to get the latest weapons. After going to silver it just becomes a P2W simulator. Grinding days just for one weapon or upgrades to be faced with opponents with legendary operator and weapons with multiple upgrades which are FAR superior than us. Yes strategy is important. But facing one with better weapons just an undesirable experience for me. Would work great as a BR though
