As Warhammer player that would've loved to play a Dwarf Slayer or a Orc Choppa, unfortunatly they were removed from the game on release...
BUT NO WORRIES
I asked a GM about it and i got this as awnser
I was planning of quiting Warhammer cause they left out the class i wanted to roll, but it was getting fixed and wil soon be putted inside the game again!
