The same than humans, Orcs Main Questline apart from the
Class Questline and SoH Main Plot.
I will be more specific this time.
▶Mounts: Think battle boars would fit the Boargen lol,
I was thinking for Orcs a big Hyena, like really big or maybe Rhinos, the
battle boars also sound good, or you can create a Rhino-Hyena new specimen.
But please make the mounts scalable to the characters size,
one thing I hate from wow is that if you are an Orc and you are riding a Wolf
it looks like the poor beast is too small for them, and they are the race
mount, but maybe that's just me.
▶Armor style: Something made of skulls and bones with metal
(like the metal prosthesis) it's great, Orcs are proud of their strength, so it
make sense that they show "trophies" from their battles on their
armors, of course this should be adapted to light, medium, mail and heavy armor
style.
▶Weapon style: I think Orcs weapons should show some marcs
and signs representing their beliefs like the Vikings and all their symbols,
but from Orc Lore. Al
▶Ingredient for crafting in Orc style: BONE, and you can find it almost
from every creature. This idea is from TESO, you need an ingredient for
crafting armor and weapons in a determined style, for Khajit style you need
"Moonstone" and for Orc style you need "Molybdenum", etc.
SIMPLE but a great element to give each Race their identity.
▶Architecture: Orcs live in dangerous places, so their
buildings should represent that, big stone, big wood, bones from big creatures,
a some metal details.
▶Language: Orcs language could be based on Turkish or
Russian languages maybe.
