Whenever I get assassinate or make them suffer, the viks are my go too. They are fast and deadly but super squishy. I think they are a lot of fun, but most opponents are not amused when half their crew is caught in whirlwinds. I find that they can do so much killing on their own that the rest of the crew can be whatever you want. Just tried Ashes and dust with them tonight and it worked super well. There is a certain freedom when your master doesn't need the crew and the crew gets no support from the master...
