The settings feel wrong in the arena, sitting in safe with full nrg unable to even attach to team mates after 1-2 seconds (Recharge spawn is way too high including full nrg). Overall games seem much slower paced and the chains graphics around the base safe is kinda stupid, there's load of tiles and other graphics to play with so just leave the safe as a square just like baseduel . Alot have already pointed this out since if you play a match in BD then play it in the league arena you'll notice the difference.
Bases are too small, compare them to BD bases and you'll notice the width is smaller when compared to any of the baseduel bases.
Needs to get resolved otherwise there's just no point playing in a league i'm not enjoying since it doesn't even feel like baseduel to me.
