Nostalrius Begins - Quality wow vanilla realm (1.12)

I'm about to start up my first character and I was wondering what most classes people are playing right now as their main? Back in retail vanilla I was a warrior and in my server there was a metric shit ton of warriors and I don't want to roll a class that's over played and have to many issues so I'm wondering what class y'all would suggest.

So druids and warlocks for both sides.

So far while leveling, most played classes in my eyes are either Warrior, Rogue or Mage.
