In my opinion, the mixture of a high TTK and the radar constantly showing the enemies position slows down the gameplay unnecessarily and makes it more stale and boring than it has to be. Especially in 3v3, most fights are lengthy chokepoint brawls. Making use of your mobility has almost no benefit, because with the help of the radar flanks are easily spotted and taken care of. With in-air-accuracy, not even vertical movement has much of a use now. Map knowledge is pretty irrelevant, because the radar will warn you, when an enemy gets into the range, so all you have to avoid are long lanes with campers at the end. Momentum control shows, that making the TTK generally shorter is unbalancable, but it also shows, what difference the absence of the radar has on the gameplay. I experience it a lot less stale and a lot more dynamic. People arent sitting in one spot as much (except when the spawns are easy to abuse), dont wait as much for the enemy to make a move just to teamshot him, when he does. They play more aggressive, take more risks and make the gameplay a lot more interesting. Map knowledge suddenly becomes relevant, because you have better knowledge of spots, where an opponent might appear. Using it for flanks can be successful and not a distraction at best. I could also imagine abilities being less impactful, because you could not always place shields/rifts prematurely and throw nades precisely at enemies' feet behind corners. I think this could at least be tested in Labs once. What is that mode for if not things like this? A less radical change would be to make it only trigger on gunfire, not movement or generally exisiting.
