World of Warcraft Advice
If you want a quick overview of what each class does in a group, look at http://epicguides.net/thegroup.html. Druid is probably the most flexible class - can be healer, defence, or offense.
Should you decide to make an Alliance character on an established server, you can look me up (Flint on the Andorhal server).
It can be fun to start on a new server. There will be lots of people your level with whom to do quests. Also you won’t be contending with an existing order. On the other hand, it’s easier to make gold on established servers.
Strongly consider taking two professions such as mining/skinning or herbalism/skinning as it will be easier to make gold. You can always choose a different profession later.
Good luck!
