But you're complaining about dispel. That only needs to be done to one person. If it goes off, the damage is done and all you can dispel is a 2 second slow. I have a hair under 9000 haste, and my frost bomb's combined cast time+cooldown is 8.88 seconds. The only time it does stupid damage is while the target's frozen, of which we have three on 25 or 45 second cooldowns, or during DF on 30. Dispel's cooldown is fine for it.
