Make ultimates scale in power with their charge level. An ultimate that is charged to 1000% is 10x stronger than one that just reached 100%.
No more 2hr blobs at last emp keep. No more stacking 100s of people together.
10x stronger would be crazy, and it shouldn't be taken to that extent, but think of the behavior changes this would cause if the framework of the idea was implemented.
Is it wrong for wanting my dawn breaker to do 120k instantly? Lol. Oh that 20k a second bat swarm tick
