I donno how well this will be received but its a subjective annoyance to me: As somebody who RPed on WoW for almost 8 years (Stopped ~MoP), seeing people act as "official" RPers of lore characters always rubs me the wrong way. You don't get to claim to be Jaina Proudmore, sorry
I mean I took aspects of characters I enjoyed in Warcraft like, Rexxar (Mok'nathal and Beastmaster), Saurfang (A veteran who's regretful over his past actions), Thrall (Hair and views on the Horde and peace.) But ultimately I still had my own character by the end of it all.
