Okay so i'm just starting out and i have a lvl 9 druid on Alexstratza and a lvl 11 or 12 mage on Skullcrusher. I like both but idk what to do in the end. Here are the circumstances:

-The druid is on a PvE realm
-The mage is on a PvP realm
-I have 50g on the druid
-I have 30g on the mage
-I know a lvl 78 in real life from school on the druid toon and he gave me that money and helps me. He is also in an extremely well known guild that he says he'll get me into when i'm like 70
-I am in a guild on the mage and they are pretty serious with raids and cool and they help me too
-The druid is alliance NE
-The mage is horde Undead

Idk what would be better in the end. I plan on dual speccing later on feral and resto for the druid and frost/fire for the mage. I want to raid and do some PvP but nothing serious. You can PvP on Pve servers anyways. So yeah what should I do? Any suggestions? Other classes? Thanks.
