IMO its easier to work as a sniper in a SAB match than in a TDM match cause...and since we have silenced sniper gun forget FFA...
-in TDM, spawn point moves with teams.
-in TDM, most of time ur entire team rush the opposite spawn point...so after 1min enemy spawn just right at you.So sniping became useless...dont forget ur LMG
-In SAB, better defense of ur own target
-In SAB, with a good spot u can suppress enemy reinforcement before rest of ur team see it.
-In SAB, u get better protection against stealth class, they must cross ur entire team before getting u out of your spot
-In SAB, focussing on a bomb lying on the ground is one of the way to get easy kills.
Like the server is not a sniper's only server, i suppose some people are going to play with other gun...and if someone want to put an ACOG on a skorpio to snipe, he's free but :S
About the rotation, i agree that we should put Bloc TDM in it( bloc sab is not woot)
