First, let's look at the main similarities between these two careers. The Choppa and Slayer were both tested back in WAR beta. Actually, the Slayer was called the Hammerer back then, which was basically a cheap knock-off because Mythic and Games Workshop couldn't work out lore issues. The basic concept of the Hammerer was quite Slayer-esque in that it was a surly dual-wielding melee DPS dwarf. Mythic decided that the Hammerer and Choppa weren't quite on par with the other careers so they were cut (along with the Blackguard and Knight of the Blazing Sun) from release. Note: the BG and KotBS were added shortly afterward.
