@Hepps Well anything is possible
But yeah level of effort to implement would be a factor but wanted to collect up some ideas first then consider weeding those out that may take too much effort.
@David_VanDyke Oh? I actually thought your suggestion was exactly what Hepps described and was what I was thinking. Group units by attack/defense value then do essentially LL for each group. Can you clarify what you mean then by:
--Combine all factors as in LL, except divide into units of 5 and roll dice to make 5s. Or, with 4s. Not as sure-thing as LL, but it dramatically reduced the volatility of the results.
