Oh, you're proposing the issue of orcs just being too "primal/violent" per the lore to be playable. I see you there and understand why you want half-orcs. I agree with that viewpoint and reasoning.
What I don't get is the half-elf argument. They are the best of two worlds. Sure, many people don't like them for that, but I don't see why they wouldn't be included. Half-Elves are definitely much more popular than both Orcs and Half-Orcs.
Also, can someone confirm 100% from in-game that if you make a Tiefling or Drow, you get spells that are not mentioned in the creation screen at levels 3 and 5? The answer I got was not exactly clear on what these races get. Also, are they changed from the base rules? Would I be able to check what they get by checking out what they get in 5e normally each?
