Haste or Crit weapon for quad boxing 1800 ele shamans?

[Selz]

I have both crit and haste weapon, i bougth the crit for pvp because thats what people told me and few weeks after i bougth the haste one for pve

Now I use haste for both

The way I see it, your already critical on your burst theirfor crit dosnt mean anything there, so the choise is if you want the next attack to crit or do you want it to hit the target faster even if your a shaman who uses frostshock after lavaburst the haste would make it occur faster sinse haste also effects GBC.. I choose to hit faster to make my burst as instant as possible, and also crit is only a chance, haste is a static buff
