POE2 gives you tokens to buy stuff that will help even when it becomes free. I play games to have fun and my friends were all buying the EA, so I thought it sounded fun.
Personally I bought Diablo 3 and was disappointed, so I didn't buy Diablo 4. I tried POE 1, but I felt it was too late to jump into. I wanted to give the genre another try. So in the end I bought POE2 EA, and it was well worth it, much more than Diablo 3.
