Seriously, serious question.
I don't understand the hype or care about Vol'jins character. I played WC3 and TFT through several times and he never stood out to me as an interesting character (and barely was given any attention), as opposed to other characters such as Cairne, Sylvanas, Rexxar, etc.
I'm seriously confused why people like Vol'jin as a character at all. I found him rather whiney when they gave him some screentime in Cataclysm and he has so far been depicted as a coward, always with his "I'll shoot you from the shadows"-comments while running away from Garrosh. (I always imagine him crying while he does that...)
But no seriously... what is so interesting or special about Vol'jin?
