Basically redundant, I find the way that https://mods.factorio.com/mod/K2SE-fusion-rebalance handles things far better than how my mod does it. That one arguably makes fusion quite powerful... but also, its fusion, so yes it should be quite powerful. This is especially important when considering that K2 now makes most K2 machines far more power hungry, so I think its pretty fair.
Small changes concerning balance, gameplay, or graphics.
