Can you really call slight changes in talents a new subclass?
Unchained is entirely different from Battle Wizard and both are incredibly different from Pyromancer and Necromancer. Zealot doing a dash vs stealth vs holding a book with most of the other talents being similar isn’t exactly a “whole new subclass”, we got build variety, sure, but changing your ult and your grenade isn’t exactly unique.
As for them being free, you’re right:
You’d just think that after 2.5 years of no new classes, the first one would be free. But then again we still can’t earn aquilas, play solo, or buy the cosmetics we want when we want to buy them. So it’s not like Fatshark cares about anything other than our wallets
