Racing on twitch with Beyond Chaos

Now that you mention it, I think tweaking the EXP curve might take care of making the randoms in zone four more doable. Of course that's mostly if the numbers are right, which is hard to tell without playing it myself. I was thinking before that most monsters could be bumped down a couple tiers in terms of difficulty, but that doesn't make sense technically when I think about it more. If progression is much faster from levels 10-50 then it could probably work out.

I don't think the bosses should be removed, but I don't think they should be endgame tier BC level. Leaving bosses as vanilla might be enough though. It's hard to tell by theorycrafting. Whatever happens, it shouldn't be "There's Guardian, let's switch to the other team because I won't beat him".
