Most of the people in my server who are at 45k-50k power who are six paths have used the Wind main, Kurotsuchi, Roshi and Asuma WB.

Maybe before i replied without reading in depth what you wrote, so, hm... what's your level?

Level is a key factor for arena because, as the arena is now, you can't meet people higher than 10 levels than you or lower than 10 levels, so if you are level 70 your enemies in ranked arena are all in the 60-80 level range. Obviously the higher your level the harder to hit six paths with no meta teams becomes.

Before i replied taking for granted you asked about azure fang lineups that work in any stage, but if you are ok to change main and you want f2p lineups then there are some choices you can try if you aren't too high leveled.

One is the lineup icebuken suggested but beware that is a 100% sure defeat against lightning treasure blitz teams that are going to become more common now (samui will interrupt your sand dust and roshi flat out dies by darui mystery combo, and also against higher initiative han, roshi, sailor sakura in the neurotoxin version (you'll be able to bring them to half hp at the end of round 2, but since round 3 you don't do anything since they'll keep your main under chaos in round 3 and 5 while spreading poison) two lineups you'll begin to meet often, depending on your level.

F2P Lineups that could work now are lightning treasure blitz teams with omoi in darui place and earth main if you don't own initiative, the han roshi sailor sakura lineup i told about before (that if you are under level 80 basically grant you close to 100% success) and the earth main or the wind main dance of impetus version with roshi, kurenai skillbroken and sailor sakura.
