The current VIP the 'Broom' has brought issues regarding its speed on events. Where you are even faster than a person with the 'Medic' Class.
In some events like water race it is hard to detect who's using the broom. Since once inside the water you don't see them using the broom. ( unless of course they are wayyy ahead than the rest, others use it more wisely and try to be ahead but not too ahead )
Admins do say the will get them banned from events but sometimes when it is only one staff hosting like Sierra did early it's hard to watch over all the players and see who's using a broom or not
