well I do love MLG Snipes (as I call it) to warm up with a BR start and Snipe secondary, I'm hoping to keep this very close to MLG rules. The first round (and hence the biggest round) will be taking place on Midship with human weapons so we start with frags instead of stickys.
If more people agree with your suggestion, I will gladly make the change, but I'll warn you that MLG Snipes on Lockout is my best game, so you can't cry if I pwn you.
for sure though, even if more people do request a change to have a snipers game as well, there will be a round that is held on Midship, because in my opinion it is by far the best map for FFA's, and there will definitely not be snipers on Midship.
Edit: Also, I don't know if you've played many MLG rules FFA's on Lockout, but it can be an interesting twist to only have one sniper on the map. usually people can only manage to get a couple kills out of it before getting messed up, but it can also be a sweet way to pull off a last minute catch up if you're falling behind.
