I think it would be cool if bronze VIP had the ability to fly. Because, one it would inspire people to buy VIP and 2 more money for the server.
I think bronze vips have more than enough perks and benefits, it is platinum vip that needs a buff up.
Giving the ability to noclip decreases the value of say silver, the majority of the people who buy anything above bronze are buying it for the noclip (and of course to support the server at the same time) adding it to bronze would maybe give people more of a reason to donate, but it'd also make purchasing silver, gold, platinum seem like a waste of money; as Sgt. Orange said platinum does need an increase in things or a reduction in price, a thread about it can be found here.
