Celtic Heroes

So I have a mage as my main, and when its lvl 85+ i want to make an alt, but idk what class. So I am posting this on all the classes. So please convince me which class I should make as my alt, overall!! Thanks for your feedbacks and opinions!

Most people make druids, as they are crucial for bosses. Or a tank(warrior), which is also crucial. But its your choice!

Most mages I know choose a rouge as an alt but maybe a warrior or Druid because after being a Mage it is very easy as a Druid

WARRIOR FOR TANK OR DRUID FOR HEALING IN BOSS FIGHTS

MAKE ROGUE!
