Before you jump at me, I will note that Ratio is very strong character no doubt about it. With decent investment, chalk can deal like 150k damage easily.

With that said though, he can be clunky to play, even ignoring the debuff quota. A lot of his damage is banked into his Ult 2 extra FU. It also activates his cone if you have it, giving even more % damage and %ignore def for FU.

The issue is that the 2 FU is like a mark toward certain target and not a buff / something that you can carry between waves.

Imagine something like this: you are down to last move before the new cycle, or enemy is about to cast something, and they are low enough. You have your ult, but of course using it would be a waste, as 2 of your free FU is gone, losing you a significant amount of damage and energy.

While this isn't exactly a Ratio only issue, it could have been a lot better had he been able to carry that 2 FU to another wave. It's not really an issue if you are not into maximizing MoC cycles so general players probably won't notice it most of the time, but if you do it definitely make or break a run.

Currently to 0 cycle MoC 12 it seems you will have to bank Ult entirely on wave 1 (even if you have full bar waiting) and only use it at wave 2, since it's way too overkill and you will not have enough energy for wave 2 / not enough damage without the free FU.

Once again, not a HUGE issue or anything, just wish it could have been better.
