i started a free to play account as a test a while ago, last year maybe, and i can sign into that account and play D2 no problem. Not my main account tho idk why, that doesn't make sense to me but i also know nothing about game development lol.

Same here but I also notice my guardian level is 1 and I was almost at 8. And on top of that I just bought beyond light, Forsaken, 30, witch queen and light fall within the month
