if you have the right raiders, on the right map, that is true, easy win.
But in general, no, it's not true. You are too slow to setup the portal in a new direction, raiders can easily avoid you on bigger maps (MoM) and you have damn short legs.
I love Shakura as a raider, but as antag, I think it's too situational. You can make the raiders slower and be a huge pain in the rear, but winning will be tougher than with other antags.
