Rift Seasons and Lighting

I think it would be cool if that the Rift looked different depending on the time of year. Snow during winter, brown and falling leaves during fall, etc. It would also be cool if it looked different on certain holidays (christmas trees and lights on christmas, free roaming turkeys on thankgs giving, dark and moody on halloween, etc). It doesn't have the be NA holidays, it could be a collection, or region specific changes to reflet their culture).

Also it would be cool if the rifts lighting was somewhat dynamic, getting darker or brighter depending on the time of day.

I know this may cause some perfmanc issues, but if you were able to toggle it, then it shouldn't be much of a problem. :)

Edit: It would also be nice to be able to choose our cmera orientation (i.e it always feels we are playing on blue side)
