This game has been a giant disappointment. Every forum I visit seems to have come to the same conclusion, with only a tiny minority who actually enjoy the game. Even among my friends, people who have never played Diablo 2 have gotten bored/frustrated with this game. Those who have beaten it rarely log on anymore.
Most of the complaining is dismissed as QQing by "baddies". Technically, I'm a bad since I haven't beaten the game yet. Yet. I have beaten act 2 inferno on my barb. Act 1 is a breeze. I do plan on beating this game, because I finish what I start. Also, I'd like to sell at least one item on RMAH to get a "refund".
Here are my issues, and these are complaints that have been touched on before in other parts of the internets:
1. Bad game mechanics such as crowd control (fear, jail, wall, freeze) eliminate micro/skill. As a meelee, it is imperative that I control the engagement. Try to fight in chokepoints to avoid getting surrounded, or if I'm in the open, continually maneuver myself so that I am only fighting one elite at a time. CC throws that all out the window. It is a dumb mechanic because it takes away the ability for me to control my character in any meaningful manner. Now, if an elite only has one CC affix, that I can kind of deal with, since i have escape skills. However, if they have two, that gets dicey. I've been chain feared/frozen and swarmed.
Now because I have no way of controlling my character, the only way I can beat such bs combos is to outgear the content such that they can chain fear/freeze/jail/wall me and I laugh it off.
I don't play any other characters, but I imagine for ranged characters, similar bs abilities that you cannot "respond" to are equally frustrating. Ranged characters are supposed to play glass cannons that kite enemies. Too bad VORTEX throws that all out the window. Oh too bad mortar one shots you. Too bad you'll kill yourself if they have reflect damage. Again the only response? Not micro (you can't). All you can do is outgear the content.
2. Bad itemization. Gearing up sucks. All gear has to have primary stat, vitality, all resistance. Its pretty much essential if you want to survive inferno. So all characters end up looking the same. You can't even allocate stat points. Gone are the interesting item abilities in diablo 2. Proc on hit, proc on being hit, crushing blow, gaining abilities such as teleportation, auras, and etc. The abilities on the weapons in D3 pale in comparison. 1% chance to freeze? This isn't an MMO where fights last 10 minutes long. They need to up proc rates. Also gone are jewels, gems that have different effects in different locations (d2 had MORE gems than d3 seroiusly??), runes, and ethereal items that made customizing your gear interesting. Like they took a serious step backward from diablo 2.
Oh and the legendaries in this game are garbage.
3. Bad storyline. Seriously, they turn Cain, who is a badass ancient loremaster similar to Gandalf, into this doddering senile old fart who has crazy theories that nobody believes. Seriously? This is after he has helped save the world TWICE? And then to top it off they kill him off in the hands of a disney character? WHYYYYYYYYYYYYYYYYY
4. No real new original content, act 4 is too short. Act 1 is a copy of D2 Act 1. Act 2 is a copy of D2 Act 2. Act 3 is a copy of Act 5 (Harrogath siege) and Act 4 (hell) in Diablo. Act 4 is "original" but its short.
5. Setting isn't dark. Diablo 1 & 2 were dark and scary. Diablo 3 is mostly bright and happy and cartoony. Not a fan.
6. Impossible to progress without using auction. Its not really possible to get through inferno without buying stuff on auction. I've only used gold auction, because paying 250$ for gear on RMAH is stupid. However, stuff is getting expensive now if I wanna gear up for Act 3 inferno. 95% of the drops in D3 are worthless, so the only other option is to farm gold in Act 1 and slowly upgrade each piece of gear. Which as I mentioned before, the gear itself is boring. All it is is just the same item I currently wear, but with more str, vit, all resist, and maybe some crit or LOH.
7. Enrage timer on bosses. This isn't an MMO. Let's not punish players for not having enough DPS to kill a monster in a few minutes.
8. Prohibitively high repair costs. They don't want us to graveyard zerg elites, yet they don't realize that certain bs affix comboes make it so that death will happen. If they want to "punish" us for death, all inferno monsters basically regen to 100% health by the time you res, so that's punishment enough.
9. only 4 players in multiplayer games. D2 had 8. That was fun. This is a regression. Oh you could have followers in multiplayer games too. Regression.
10. No investment in character. All characters of the same class are identical. you can't allocate attribute points. Skills are trivial to swap in and out. Not that it matters, since in inferno there are very few viable builds, and everyone is geared pretty much the same. No possible "fun" builds like you could in D2.
Bottom line the game is just not as fun, and a serious step backward.
