People say you should always buy with your team, but what if for example:

Calling a save (e.g. only having enough money to get cheaper weapons bucky etc...) but my entire team forces / full buys instead and has no spare money

What should I do in these situations if I don't have any weapon utility (e.g. jett knives, chamber op), especially if they don't listen

Should I spend every cent I possibly could to try and keep up or just save the round?
