can a rogue sneak attack more than once/round?When you start messing with ways to bypass the action economy limitations, the burst damage martial classes become pretty ridiculously powerful. A battlemaster fighter working with a rogue or smiteadin (technically a caster, but using their spells to enhance melee instead) gets pretty ridiculous, especially if the damage dealer also has the Sentinel feat. A rogue sneak attacking 2-3 times per turn is going to be pretty hard to match.
