Just incase you didn't know, 4 classes were held back just before beta. 
The 4 classes were:

Black Guard  (dark elf tank)
Empire Knight of the Blazing Sun (empire tank)
Choppa (greenskin melee dps)
Hammerer (dwarven melee dps)

So in an interview with Mark Jacobs, he said in addtion to Black Guard and the Empire Knight of the Blazing Sun coming back next month one other class that they held back will also sill be coming back, but the fourth will is getting replaced. 

I believe that the Hammerer is getting the axe (pun intented)  to make way for the class that every real Warhammer fan wanted and the one that was shown in the first video... 

SLAYER!!!

For me nothing says the Dwarven army like the Slayer

what do you guys think? Will it be the hammerer or the choppa that gets replaced?  What class would you like to see replace him?

Im thinking the Choppa will be replaced because its really just the black orc with different skills, visually its exactly the same. They probably are looking for something visually more appealing and different.

Well taking the fact that all the classes in the Warhammer online  are translations of units in from the table top  the only other Orc s you chould use would be a Savage orc or a Orc Bully.   The Bully would be intresting support class.  They have other units to pick from but all the other units are Goblins and i would think they would want to have 2 orcs 2 goblins not 1 orc and 3 goblins.

My bet is that it will definitely be Hammerer replaced with Slayer.  The reasoning is simple:  focus on dual wield melee DPS.  This keeps the two handers in possession of the tanks, and melee DPS will do what it's SUPPOSE to do.
