If y'all didn't know, sorcerers lose a meteor when using Meteor Swarm with Quicken on.
When you take Quicken off, you get the correct number of meteors again.
This issue used to be a lot worse but I bug-reported it and they made it not-so-bad in Update 5.
Still, I would like to get full damage from my spells when using Quicken like the wizards do.
P.S. Frost Lance only has 2 lances instead of 3 with Quicken on, as a sorcerer.
