Yo Sim, I'm sorry that the Oasis employees are mocking you instead of helping. There's no strategies for 170 vs 390k, it's a very bad joke.

IMO what Matsuri really needs is free revivals to survive the matchmaking lottery. And what SWB needs is to become like Training Grounds. And what Arena Matsuri and Arena Sage need is better rewards (like their standard modes or better) to make it a bit more fair.

Every matchmaking system has its disadvantages. If they introduce a power-based matchmaking, you will see people stacking their 1 ninja and going naked on the rest of their team (or without a team at all). So from 1 pathological situation to another. I mean, stacking is already a thing, but not to this extent. Not to mention that spending on power would become useless.
