Having a president in the mod shop has a lot more impact on the gamemode, to warrant keeping them in. If the president is in a mod shop, no player can get to him, and on top of that, his blip will be showing in the 'wrong' spot, leaving many people confused or frustrated. The mod shops are not vital to the gamemode, and there's not a lot of people that use them anyway.
For the people that do want to tune their vehicle, they can be civs and still have access to the mod shops. A custom menu would just take too much time and effort for something that's not really part of the gamemode.
That's all cool, and I understand those ill effects but you shouldnt really make classes like terrorists suffer, who need to catch up with president.
Yes, NRG is a very good overall solution and Terros have the most of em at spawn, but they dont exist in County Maps and can barely fit 3 people, let alone a team like sultan. [Average difference between stock and nitro'd sultan can go up to 10-20 seconds iirc]
Nitro helps significantly and a Infinite Spamming Nitro FBI rancher is nigh infamous as NRG in being able to keep up. The server will devolve to NRG wars like the armor wars for cops vs terro. Almost already has been by 'surviving' regulars
Forget hydraulics use of prevent tipover, atleast nitro is more used,almost every VIP Spams it, and almost every regular prefers to have a nitro'd car for anything below supercars. As stated multiple times, Driving is still a core feature of the GM.
Aren't the filterscripts for it already available? Is it not possible to use them? (or are filterscripts useless in this case?).
