The fact that there is no AH is amazing. Think about it, you now have an item grind, you won't amass 1-2m, buy gear on the AH and never find an upgrade again for yourself. This here is what will make it fun.
You will actually be excited to find gear, instead of just going to the AH to sell/find it. Legendary drops should actually make you jump out of excitement (especially if they bring over the upcoming legendary patch). You'll be able to play with friends and just pass gear around, I'm just hoping there is a little more item storage, ps4 preorder bonus? :)
There's a lot of hate for D3, but in its current version (besides the AH existence) it's really fun and polished quite well. I truly believe if this was released by anyone other than Blizzard it would be very well received. Bringing over all the recent updates that PC version has will make for a good game at time of release; can't wait to grind paragon levels from the comfort of my couch.
Offline HC? Yes please! I love the thrill of playing HC but I have only lost characters to lag so far on the PC version. A little on the fence for first come, first served drop system, would be cool if there was a toggle for this, but whatever as long as you're with friends.
Now I just need to decide what version to get, guess it depends on the PS4 release date. Hope you guys are excited as well!
