Rework the class system to work without a crooked fix.
Add integration with sourcebans/material admin/vipcore by r1ko .
If you do not want to do this for free, open the fundraising

The problem is that the plugin has to be compatible with different game modes, anything that changes without planning affects other servers that use different modes.
Best would be a zombiereloaded private for you, or separate the class system and let people define classes and skins with other plugins or in other ways of their own, like I did with the sound system.
About integrations. If you integrate too much functionality into a single plugin, it becomes too cumbersome and complex causing delays even on the best servers.

Integrations can be made modules?

I would take part in fundraising, but I won’t be able to buy personally at European prices from Russia

P.s I just can't find that much money
