Go druid first. At 14, you get a powerful charm animal spell that will help you power level all the way up to 23-24 in no time. Unlike enchanters, druids don't need no stinking charisma plus they got snare and heals! So learning the ropes of solo charming is way easier on a druid.
If you like the charming life, you can always move on to an enchanter alt at some point

If you do go druid, do pick either wood elf or halfling so you have the Hide ability. You can use it to break charm and oh boy, it is amazing. Here's an example as to why, after which I'll shut up. Say your charmed pet drops below 20% so you snare+fear the animal you're fighting. Once the enemy is dead, you can just click on Hide until it succeeds. The mob will start running and now you can either finish it with a nuke or charm another animal to kill it for you. There's no need to stand up and cast invis (25-30 mana plus a possible mana tick!) plus hide will let you AFK for extended periods of time.
Good luck.
