This is a crazy theory of mine, hell it may be clear as day to everyone else here - I think stamina will play into how your players perform in game. I also think stamina also plays into how your players train. When I see the training intensity values, with intense being +3 en, and the relaxed being +15 en that says to me that intense makes your current energy refill slower, but whatever you are training increases at about a 20% greater rate. This really means something after a few weeks (if we keep playing that is). Now if I'm assuming you guys had the same priorities as me, you wanted to put your points into other stuff, and not stamina when creating your character, you may have put in a token point but nothing of any value over the original newbie stamina value. So we are all low in stamina. In my opinion, if we all make the investment in training stamina intensely for a week or maybe two, we will be able to train harder for real tangible values that have actual payoffs ingame. This may cost us some wins or stats in the short term, but our players will be better long term (if that matters to anyone)
