So which class/profession is the most common one?

[Blighter]

I'd hate to end up being like everyone else, or are there an equal amount of each one in the game?

[Lollan]

Night Elf Hunter and Undead Rogue are really common.

[ItsNoot]

Hunters are pretty common ... BUT thats because it makes the best PvE solo force you can ever have. If you think your going to do a lot of soloinng, hunter is the way to go.

im gonna be a blacksmith and a miner cos i like making cool armor

[Svperstar]

Most blacksmiths go weapon, so if you go armor you should have a lot of potential clients

Theres a reason most smiths go Weapons, I learned the hard way, Armorsmithing suxors compared to Weaponsmithing :P. When the time comes late in the game Scottg make sure you choose Weaponsmithing :P more profitable and more plans ATM

The best profession hands down is Engineering. Mining supports it, you need some leather too though.

Alchemy is a good skill as well, if you want to do it, do it :) (Everyone needs potions). I do Skinning/Dragonscale Leatherworking, it's practically completely useless (Skinning does make me money though).

alchemy is not only useful but pretty simple. almost all of the potions are Herb 1 + herb2 + vial = potion
