If you don't like to loose then start building better lists.
Don't come in here with your holier than though "I just play for fun" attitude and then complain about loosing to a better list (and if you call that
IG list a leaf blower, you really are in for a shock). If you guys just play for fun then why do you always complain so much when you loose?
Stop expecting other people to dumb down their armies just so you can win with your scrub lists, especially at tournaments. Don like it? Then don't show up to tournaments and just play pre-arranged games where you can define the rules.
I'm still new so I don't know, but is there a current wargame that has predetermined army the player must use?
Yes there are, they are a new invention called "board games" I suggest you look into them.
