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. Pair this with me always being purple-geared, I feel like I'm just n00bstomping in the 1-49, so I can understand why the transition to the 50's brax might feel hard. 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, this means battles last longer and fights are more challenging. 1-49 is EZmode for me, so while I do enjoy stomping every now and again, I'd be lying to myself to say that's where the real pvp is.
Do the dailies/weeklies, do some HMs to gear up instead of writing whine posts. You'll gear up fast enough. Save up 1k/1k + 1 champ bag before 50, you can get a few pieces right out of the gate. You can also run some FP's. Getting champ gear is easy; and BM is not much better than champ.
