As a GM I have to make choices that some of the players don't like. This current one is not allowing the stamina system into my game and dealing with the player that is fighting me 100% of the way. I don't want to deal with it because it's a lot of stuff I have to take into consideration when building an encounter and while I think the system is a neat idea I'm not ready to play test it in the current campaign to see if it is right for our group.
But this guy will not take no for an answer and has three years of debate on his side. So from one humble GM to another can you guys please tell me everything bad or poorly designed about the stamina system so I can get this guy off my back for a campaign when I'm willing to test it out?
