Ok so every time I open any type of crate I get a hero I already have, what’s going on with that cuz I want new heroes I don’t want the ones i have from the crate
It’s the nature of the crates. It’s random. I don’t know how many heroes you currently have but if you have 30+ there’s a bigger chance for getting a duplicate.
You will unlock Wesson soon enough from the co-op raids. 
I wesson got it in the purchase of 899 of the box was luck like panzer gg
