I paid for the graphics card, I want to use the WHOLE graphics card.

In seriousness, as beautiful as this game can be a graphics update is something people have been asking for. Many MMO's have to do this at a certain point to avoid looking dated if possible. Even WoW overhauled their character models with an extremely dated and near exhausted game engine; granted making the players look nice made looking at the environments, gear sets and enemy models look a bit out of place.
