A stock glacier has 5 crystals that deal 55 damage each with heavy falloff. In theory you can do a max of 275 damage but that'll never happen in practise since the glaciers are too far apart and realistically totalling at around 215 damage if they are hugging the centre of the glacier. Fissures adds an additional tick of 22 damage per explosion (that has it's own range profile) making the max possible damage 385 but again, that won't happen since even if you are standing by the centre crystal, the falloff of the outer crystals comes into effect, and can only kill a 52% DR super if they have 0 resilience. Touch of Winter throws all of this out of the window by not only adding an additional crystal but also changing the formation to a more tightly packed hexagon. Total damage is now easily achievable while dealing a total of 330 damage and 462 with fissures with a bigger freeze radius. Don't nerf glaciers, it'll nerf the dive combo but it will nerf the other two classes more (especially Behemoth). The point of this is to counter those who use the argument "Don't nerf the dive, nerf the nade instead". P.S. These numbers are on unfrozen targets, if you are performing any of the following moves, you'll incur a 90% shatter damage reduction: Shiver Strike, Howl of the Storm, Glacial Quake and Shatterdive.

My suggestion is that the glaciers takes time to form in stages based on and deal damage based on crystal size accordingly. That way if a hunter were to throw a grenade and shatterdive immediately the damage would be minimal and the target would survive. If the crystals are fully formed at the time of the shatterdive it would kill even a super.
