Destruction Staff type redux

Koshchei

The last thread I saw on destruction staff type was back in June, and full of contradictory information.

Are all staves relatively equal dps now (the only difference being the situational advantages), or is fire still miles ahead in both dps and mob control?

Does the situation change if you're a sorcerer, given the disintegration passive?

Clunan

Fire Clench is by far the best in terms of CC, also the burning proc adds to fire's DPS, and as a lot of the playerbase rolls a vampire, fire is pvp friendly.

It depends on what status alignment you want. Fire is especially good for the extra DOT and against pesky vamps and stuns with Destructive Clench, Frost slows/roots, Lighting can disorient/reduce damage output.

I don't see disintegrate proc that often but when it does, it's nice, it also forces them to res somewhere else as I believe you as a pile of ash are unresable by players?
