Thanks for the comments again
I know the leveling with a mage must be faster but in my case i had no uch class.
And for the point of using blizzard, i know its really useful once you get it but using this method you can take any mobs like the casters. Just wait for them to use all their mana on the healer helping you and then theyre going to be gathered around the high lvl.
The problem with blizzard as a low lvl is the fact that you dont have ice block or any mount to gather the mobs and you cant take caster/ranged dps
