@Orakh you got the point. I'm totally agree about put target lock down. That, maybe, could solve some OP characters issues.
Thought... another way that I think it could make the game more dynamic is a horizontal map type (corridor) than vertical. Teams got to push their enemies back to the start area. Maybe it will be hardest to do for those current maps but I believe that this idea could serve as a brainstorm to the devs for the future maps.
