My main hopes are like
@flibby , better deeper itemisation and also better endgame, i was talking to my brother
@Smudge about this and he's of the same opinion that the skill tree's need to be better than D3 and deeper, and the endgame as well.
From all i have read it sounds promising, i would imagine the game is fairly basic at the moment, they know what classes they want, they know the story they want, the lore etc, and art style, but they are probably nowhere near finished on actual game play mechanics, core skills etc.
One thing i liked about D3 was at the start you had a lowly 3dps weapon and by endgame you was wielding weapons around 4k dps, i hope we get similar, and not stuff just doing overinflated numbers right off the bat, which im guessing wont happen as Blizz is pretty good normally with progression itemisation.
As someone else pointed out the game looks slow what we have seen so far, but this is probably early into the game, like D3 as you progressed generally you unlocked skills and or stats / items that would increase your moving and clearing speed, so im not overly worried about the perceived slowness of the game right now.
One thing D3 had that D2 never had the chance to have is a lot of core streaming community, people that live and breathe the game, yes D2 had a lot of theorycrafters as well, but with D3 and the popular nature of Youtube, Twitch etc theirs a lot of higher profile streamers playing this game, i just hope Blizz engages these people to help make the game be the best it can be, and id actually like to see them do a good alpha and beta of the game on the way to full release, to really home in on what people do and dont want.
The dungeon stuff with keys sound great, almost liked they ripped it out of Wow Mythic dungeons, and lets be honest, it will add a new layer of complexity to the game, which will be a good thing. There is nothing wrong with taking systems from other games if those systems are good and popular and actually are engaging and work.
Glad there is no AH and Microtransactions are supposedly limited to cosmetics, tbh i wouldn't be against POE levels of Cash shop, a lot of the stuff is QOL items and fluff, which suits me fine as i rarely buy any of this stuff.
The Druid looked good fun, they have said 5 classes right? we have seen 3, Barb, Druid and Sorceror, guesses on last 2? im guessing a Necromancer and a Paladin / Crusader type. They'll no doubt add expansions and DLC with more classes along the way.
I just hope that we have an engaging story mode, and then something like D3's end game modes that keep you logging in for more, and they dont balance the game around full sets of gear as that got really stale for game play, would rather have a bazillion legendaries with unique stats that make you really angst over what you pick and choose to use
