I'm not pro but im not new, i'm level 30.
Looking for Ultraespaedeh and Suppa Nobaahh!
The addition to level 50 might be good
But idk does liran want to implement it or not?
BTW, years ago, there are 150 level cap in Supermechs.

To be honest I have no idea why levels 31 - 150 were taken out, there was really no point to.

I say add 30 more levels, but make them extremely hard to achieve (for average player). Like level 50 requires 1,000,000 exp and rewards a mythical box.

Every million exp after that will reward a gold box and a level up, up to level 60, with requirement of 11 million exp.

That should keep everyone busy for awhile
