Sylvanas and Garrosh are two of the most controversial characters in the World of Warcraft -- both have certain parallels in their stories and character developments. Both were once extremely popular heroes and proud warriors who fought against the Scourge to defend their factions, and later to protect their respective peoples, the Forsaken and the orcs, from the Alliance. Both eventually fell prey to the weaker parts of their nature -- apparently becoming corrupted or otherwise turned against their former loyalties, although some kind of redemption seems possible for them, at least in the realms of death if not in those of life.
Which is generally more popular among the player base, and why? Which was better developed, and which had greater potential? If Sylvanas is more popular -- why is she better received than Garrosh, given his compelling backstory and his similar initial sense of honor? Can they be redeemed at this point? Or are they truly beyond any kind of redemption whatsoever?
