Ooops. I missed this initially, Orogun. My apologies!
In general I’d say Orgrimmar. More specifically the Valley of Honor. However if your main will be a blood elf and you would like a more elven-centric experience, maybe check with Moranai and the Convocation of Quel’Thalas group. I recommend them since I don’t have any blood elf characters and they could advise you better than I. Welcome to MG Horde, Orogun! I’m glad you’re here.
