I personally think the exact opposite, I think the reason games feel so slow currently is because of the current radar system (and 3 peeking, but that's a separate issue). The radar's range is insane and reinforces heavy passive play as you can tell where opponents are at all times and people are hesitant to take a fight that is not favourable, therefore not wanting to take flanks, etc. In a trials/3v3 setting being able to tell where the other team are playing basically at the start of the round actually slows rounds down a lot when both teams are on a similar skill level.
