So I've been playing against Tau a lot recently and I just don't know how to deal with Riptides efficiently. They seem to be under 200 points, 5 wounds, 2+/5++ with too much firepower to ignore. D-Weapons would be the best of course but it's not very easy to get them in range. The other options are starcannons and pulse weapons, and those need a lot of fire to bring down a riptide. How do you guys recommend taking them down?
