Do we have to be orks? Could we instead be grots? If so, do we have to be basic grots, or can we have special gear? Examples in order of potency: mortars, grot tanks, killa kans.

Would we be allowed to be stealth boyz? How about an odd boy? Loota?

Orks come in a wide variety of shapes and sizes on the table top, but truth be told they're like most other races. Most variants of ork are just boyz with different varieties of shooty/stabby kit. So, what are we allowed in our selection of weapons/wargear?
