I want to level a rogue soon! I think an orc or a goblin would go best looks-wise. Any recommendations/ tips/ cool facts/ etc?
I just race changed my Rogue to an Orc male and I rather regret it - I’m a little to thick. (I was an undead and had immediate buyers remorse over the race change.)
I think you should strongly consider rolling a Goblin becasue its really nice to be small and agile on a stealthy class. Also Goblins recently got a graphic overhaul along with Worgens.
(And they are one of the least played races and that makes them cool imo.)
Always troll 
Goblins have the best stealth animation and go great with the pirate theme.
But my main is a blackrock mag’har orc so it’s a tough choice
