So I have been thinking for awhile, and I noticed in the Realmslore there is nothing about Wild Orcs. We have a great deal on Stargazers, EFU:A's other unique subrace, but nothing on the beasts we kill so readily on a daily basis. So I propose, if possible and obviously not at the top of the priority list, a post is made on the subject.
Now clearly there wouldn't be much common information about Wild Orc's or their culture. But there would at least be what they look like, why they are different from Mountain or Grey or Deep Orcs, some very basic easily recognizable cultural facts, maybe even some Wild Orc name examples.
Again, this would clearly not be a priority topic, but maybe something that could be done by a DM that has interest in the subject, and some spare time on their hands (when does that ever happen?).
Me am grog. Grog like hit things with spear. Then grog eat.
Slayers Guide of Orcs actually has a great deal about Orc culture, pysiology, etc. Beyond that, read up on Gruumsh as much as possible.
I'd prefer them to remain the way they are unless a pc seeks out information on them. One thing to note is that they seemingly do not have light sensitivity, which other orcs, particularly orogs would deem to be a very ~interesting~ trait. Orogs for example believe half orcs to be superior to mountain orcs in utility due to being able to operate in sunlight.
I think this is for player's to develop themselves as they apply to play them.
Spiffy has the right idea. Just some very basic cultural notes could be amazingly helpful to anyone trying to apply for one, and entertaining for others to read.
