Hello,
I think rollerskater skins should be exclusive to donators only, because it is a bugged skin (has ridiculous movement speed) and I see at least 5 people using these skins every day. Okay, they are slow in the grass, but all of the cities have 95% anything else than grass/sand, which makes it a no brainer for some people to abuse this skin. Also, it can be used very efficiently to escape cops on foot during a chase, because a cop skin can't bunnyhop faster than a rollerskater skin can run, so this makes it alot easier for the people who use this skin to escape.
Thanks.
