Vikis crew only really have to worry about shooting heavy crews. Against any melee based crew they will pretty much slaughter it. Ronins can't be charged so they can run up as fast as possible to capture objectives, Viki's with the right upgrades can slaughter anything, soulstones are awesome for them as you can always make sure whirlwind goes off. Being able to pre measure everything means you never have to worry about if your at the right point to hit everyone with whirlwind. They are one of the crews that really benefit from 2.0 rules changes.
