Least favorite: Customization - dayum, those standardized poses be ugly. Also shitty customer support, overrated species (Draiks, lookin' at you), and overloaded/epilepsy-inducing lookups.
Most favorite: Plots, board drama, occasionally funny item descriptions.
I agree on that. I was so disappointed when they converted the pets... soooo ugly. They should bring an option to convert it to the old style but that's never going to happen.
