Your equipment is so powerful and combined with haste I generally just don't worry about it. The thing I'm worried with DKK at max cycles is it becomes so quick that the most competitive strat will be to quick every battle and rely on RNG. Bothering to cast haste might ironically be too slow.
Again not a deal breaker for me, and it doesn't apply to either champions or dark queen (once I finally get around to running that), but DKK in particular would not be fun to run at max cycles competitively.
Is it worth creating different categories? I'm ultimately fine with whatever is decided but I haven't seen it come up in discussions so curious if that is something worth exploring. Also will be interesting what if any changes the steam releases make.
