Hi guys so i just got back into dual boxing.

i had a tripple shaman team, but only lvl 20.

Now, i wanna make a mage team, but only a 2x mage team!
still cashing in last 2 months of school, and saving money for my big vacation.
So i will be 2 boxing for a while

my questions are :
how do u guys cast blizzard on both? is there a mouse addon or w/e

Since i'm not raffing these mages, i need to quest, any ideas on how to get quests open on both chars fast?
and how to hand them in quickly?

to get my quest i could share and make an accept macro.
BUT to hand in? i got no idea

Also any tips for 2 boxing leaderless? because i still have problems with this.
