Haste typically lasts more than one round, and equates to 42% of agility, so imagining you have 100 agility (a lot, but possible) it would be 4.2 CT every cycle for 3 rounds. I think this works out to about 93 ct. Quicken gives you 100 CT immediately, unit will act at end of next cycle and retain any excess CT. I'm glad this prompted me to calculate this out, I might turn haste off
