I wouldn't exactly say that. They don't push for high-end visuals, but it doesn't necessarily mean they don't push the hardware. The reason why most MMOs try for mid-end graphics is simply because having 100 players casting spells at the same time will push your hardware.It's not that you can't it's just that people into hardware that pushes the envelope are generally mainly interested in games that push the envelope, something which MMORPGs don't do so it's a bit of a miss-match.
You want my blood? Come then, dog.I thought I smelled the stench of alliance pig.
