I think the only "unfair advantage" in war game is "un-dead".
Any other, e.g. NV, torch, 2 J vs 1 J, uneven number of both side, walkies, etc ...
They only make the game more challenging therefore more interesting.
To me ... that's fun.
Certainly, if any player only wish for "winning" but nothing else ...
I recommend this kind of players should only "race with 6 years old or less" ... to secure a sure-win.
