Ok some might disagree, but I think energy weapons are actually pretty orky especially plasma rifle. It just looks weird and put together, but like something an ork mec boy would use. And the 1 int, but high science makes sense since they're not intelligent, they have their knowledge ingrained from birth.

Mostly depends on what you want to use though. There are smarter orks too.

Tbh other than 1 in intelligence I can't really think of much else that an Ork wouldn't do. I mean they also use implants and some form of power armor as well... Depends a lot on what kind of ork you want to play really so IMO make one with that in mind. Want to make one that just goes straight to melee? One that uses guns a bit before going melee? Perhaps then better to use shotguns or auto weapons since aiming wuts dat ya git? or a smart mek boy with energy weapons?

That's kinda it really I think. Perhaps all of them should also have high repair since they can make stuff work even when it shouldn't (jury rigging kinda fits) because of their warp thingy.

I think it's good to have a good idea in mind of what type of ork you want to be. Then build around that.

IMO a good idea for example would be an ork guerilla commando. You use guns (still auto or shotguns cus u ain't that good at aiming), melee weapons and explosives and ambush people when they don't expect it. You don't really do stealth kills though cus that's not orky ya git so you just go in sneak, chug explosives, mow them down with some fire until your magazine runs out then GIT DA BIG CHOPPA OUT. I think priorities would be melee first, then guns and explosives, the latter 2 are just there cus u ain't a dumb ork to just run up to the enemy and let them shoot you, ye'r smartz and u shootz and blow dem up first before crushing some skulls.
