Champs bundle vs Chance

Should I get the champs bundle or risk it and wait for hopefully Forsaken Vandal and Rgx butterfly knife

chance

I'd say it depends, but in the end if you are having doubts about purchasing the Champs bundle, you should NOT do it.
Personally, I fell in love with it as soon as I saw the reveal, plus it feels timeless, like I'd be jealous in a year or two if I saw someone use it.
