Seble, regarding stamina, I've contended that irl "stamina isn't a major issue," but let clarify my thoughts. 

It is--only to the degree that it's based on the number of kids playing.  I don't think the solution is to lessen the impact that fatigue has on the engine.  IMHO the solution to lessen the variation of the players.  And I think those are two distinct things even though you've said that both can accomplish the same result. 

For example, it's my belief in HD, 6 guys with 100 stamina would be equal to or perhaps better than 8 guys with 75 stamina each.  You could correct me if I'm wrong all else equal. 

IRL the 8 would be miles better off than the 6 simply based on rotation and rest.  IRL 8 guys with 65 stamina each would be better off.  At least that's my opinion.  Lessening the value of stamina in the engine doesn't account for this because it doesn't take into account the rotation.  It's more about the number in the rotation than the value of stamina imho.  Thus, having less variance among players would be more realistic.  

So to clarify.  Stamina isn't an issue for teams or players as long as the rotation is there, regardless of a players stamina (which irl is pretty hard to measure anyway).

Thanks.
