I'm in Act 2 on Cruel and it's been a lot of fun in general. Just had the game d/c in the middle of a boss fight after about 2 minutes of most everyone standing still (I kept running around in hopes that it might somehow reduce the chance of my dying when it "caught up"), though, leading to yet another "singleplayer!!!" moment
I certainly won't play Hardcore with that kind of possibility on the table. "Oh, by the way, for the last 20 seconds you weren't actually dodging monsters and stuff, you were instead just standing there like a moron because of a hiccup in the internet connection. You'd probably be surprised how much damage that boss can crank out in 20 seconds. I hope you didn't
like that character!" Though I guess in PoE you don't lose the character, it just gets "demoted" to a non-hardcore league?
Other than that my only notable concern is that the game doesn't seem very challenging. The Act 1 boss on normal difficulty pushed me pretty hard, and there were a few random-rare monsters with nasty spells that almost got me, but other than that everything (including the Act 1 boss on cruel) has been pretty easy. My only death was to some non-boss monsters in an Act 3 sewer because I got sloppy while running through monsters to get to the next map. Possibly the witch+minion+fire approach is a bit OP? Or is it not supposed to actually get hard until merciless? Or the "maps" you can pick up?
Not that I mind a relatively-easy game, just wondering if I'm missing something.
