Ok here goes...
I am a level 24 BE mage, (frost) with good gear for my level - Staff of the Sun etc.
I am really struggling with it. First I find it very hard to deal with more than 1 mob at one time. Frost nova is great but has a longish cooldown so I can freeze the mobs to keep them from melee range but after that I am in trouble (especially if it is resisted) I try to polymorph one enemy but that only works on certain types of mobs and they will usually come at me after me before I have killed the other one :(
So I am stuck with 2 mobs on me - one with full health, the other with 1/4 health...so I use instant casts (firestrike and arcane explosion)but before I know it I am out of mana! I try to use my mana shield but again my mana is down to nothing before the end of the fight...
Also I am having to constantly sit and drink to top up my mana - which is so disheartening when my friends Warlock (same level) just runs off to the next one with full health and mana!
So why am I playing a Mage? Warlocks get more health + abilities to Lifetap and drain mana + a bloody pet to take all the aggro, so whilst my friend is happily taking on 2 or 3 mobs at a higher level I am slogging my guts out for little reward...
Please help/flame :D
