Blizzard macro question?

hey guys, first time poster. what im wondering is my mage is my second box, and i was wondering how i could set up Blizzard so it would just cast 10feet infront of the mage? is that possible. or cast it at the target that the main box is targeting? or should i just stick to frostbolt's and firebolts?

There are a couple of ways you can do it,
Here= A neat macro to easly cast ground targeted spells (hurricane,treants,blizzard etc) is one way that works well for me(Im using for Death & Decay)
or you could just alt tab realy fast :P
either work.
