Randomness and insufficient resources for leveling up in the Colosseum.

At the beginning of this era, I actually thought it was better than the last one, now I've changed my mind.

I noticed a pattern where you could normally progress an additional tier with each new release. I think I'm still on tier two for a couple of the bosses. The damage output is ridiculous - and I know you shouldn't blindly say "this feels bad" if you don't have the evidence to back it up, but this feels worse than before.
