The one major thing wrong with this game? Is it desync? Gambling instead of crafting? BIS uniques? path of life nodes? trading? No, it's none of those things.
The thing this game needs is treasure goblins. I'm sure a lot of you played d3 and really enjoyed treasure goblins. I fondly remember being partied with a few people and whenever we saw the amazing little goblin we would all scream "GOBO" and everyone would get super excited because even if they didn't get a lot of leet gear from it they still got quite a bit of currency.
The equivalent in this game is either inner treasure mod- league specific, or large chests. Large chests are terrible and actually demoralizing to see because the drops are so horrific. I understand why the drops are bad but they are not a viable substitute for treasure goblins.
This game needs real treasure goblins. They should have increased drop rates and always drop a few orbs. Doesn't have to be exalts and eternals. It could maybe drop like 4 or 5 chance orbs, a few chromatics, and a fusing or something. Make them rare enough so that they cant be abused but occur enough so that when you play the game to level 70 you at least see one or two of the fuckers... Inner treasure mod is ridiculously rare.
My suggestion would be to setup a system where goblins have a LOW set chance to spawn. This chance increases "x number of mobs are killed" AND "x dmg" is done by the player. Once a goblin is spawned no new players can join the party until it is either killed OR the party leader accepts the prompt on the screen to despawn the goblin. These things will help stop abuse cases.
People won't be able to hop from zone to zone because the chance of spawning a gobo will be very small if you are not doing dmg AND killing mobs. People wont be able to all search for gobos then invite people to their party to all kill it because of the second stipulation.
