outside of the obvious like save rounds and shit like that, but like is there a "do not buy an op" moment? i like chamber but i neve buy an op because as expensive as it is im always scared off from it. if i die not only am i down a fortune i may also be giving it to the enemy team.

but i feel like its also really easy to go wrong and i dont want to just buy ops when i shouldnt. but i also dont want to NOT buy ops when its perfectly viable.
