When to stop gathering haste?

[Fuzzyboy]

I think hit is better than haste until you get 200+ hit, then i go spell power > haste.
Hit is good because I hate when my lava bursts miss. Crit is nice because everytime a crit lands, my spell power is increased by 10% for next two casts. So getting to ~30% crit with buffs is good. After that, take haste gear as long as your hit > 200 / crit > 30% / spellpower not lowered.

I'm assuming you're kidding? :-)
