Wave is more a druid than a sorc weapon because of MCL issues. IMO, ice sorcs are best with two sentient set-ups, one a Dino qstaff with ash for most questing fitted with a mix of DC and DPS fils (raid cha, dragonsoul, frozen wanderer, etc.) and one with two Dino debuff sticks (ash and vuln) for boss melting, fitted with pure DPS fils (elemental avatar, dragon soul, frozen wanderer). Keep a non-sentient ooze/salt pair, and a non-sentient affirmation swap (ideally snapshotted). If you like swapping a ton, you could run Wave as your boss weapon too, but IMO the lower rotation uptime because of attention and GCD issues is not worth it.
This level of separate weapon setup is only relevant if you're looking to optimize your single target DPS past r8 or so (i.e. you're filling the boss/doom DPS role in high reaper parties/high reaper solos).
