Do you still use frost bomb? I simply think for 90k dispellable damage is not worth risking a frost-lock. Smart people pop cd's when they lock you out of frost. Have you tried haste/nether tempest? You basicly become a ranged warrior. Non-stop 60-70k spamming with a 1 minute cd as your primary nuke. -frozen orb- And by the way, there is literally nothing to cast when you run that thing, so you end up casting some frostbolt for lols when you're completely free. And its damage is meh.
