I prefer the 50's brax tbh. In the 1-49 brax on my alts, I find that a lot of players don't know what they're doing (more so than the 50 brax anyways), queue up at level 11 and spam their basic ranged attack, lack a lot of their abilities possibly causing one side to be imbalanced. I feel like I'm just n00bstomping in the 1-49. Capping a turret, scoring, or planting a bomb in the 50's brax feels so much more rewarding. People die much slower in the 50's brax and are generally more organized. I think that's a good thing.
So personally, no. I main a Shadow and I am not foregoing the 50's bracket for easier PvP.
