Returning Player Qs

[kcimythgim]

Hey y’all, I’m returning after a long hiatus. I haven’t played since the lvl 76 cap, and it seems like a fair amount has changed since then. I’ve seen players talk about ESB, a “knock-off” ESB in the lvl 80s, and some new Max level ESB. How many different weapons have the cannonball proc now? Also, have these “knock-offs” tanked ESB prices, or is the ESB still a very sought-after item?
