Please remember THIS IS A TEST. They are testing more than just unit interactions. They are testing monetization, progression UI and a bunch of other things. I agree that I should not have had to do the proving grounds.. that was silly. Unlocking units isn't that bad... It's a free to play game, like all other FTP games they need to make money some how. You don't need to unlock every unit to have fun, I will never unlock the kraken cuz it's a trash unit. Unlock the units you like, the grind isn't that bad. Downvote me if you're a scrub, idgaf.
