For some reason in my last post the word h.a.r.d.co.r.e got censored wtf?
If they installed a better spell system(Something based off of Diablo 2 or 1),
Installed a better item creation system(Something based off of wow/Diablo 2 combined or perhaps just diablo 2),
Installed a better item effect system(Base that entirely off of Diablo 2, it was awesome, no need to change it),
Installed a ha.rd.c.o.r.e mode once the servers were good(I died 5 times due to server disconnection, and that's because their servers went down). Or better yet made you disconnect straight away from the game should their servers fail, until their servers were reliable.
If they took their time with the last 2 acts it would have been better too. They had a good story line but, the last two acts seemed rushed. It looked like they were just trying to make some deadline and produced half ass
****. Which is total s.h.i.t. because it was released a year after they were supposed to have it made.
Their item market system was also trash, it got inflated sooo fast, the whole D3 economy broke within the first month.
I can go into detail about their item system, spell system if you like Chakra, what made them total trash, but those are the bits I found wrong. They did alright making it a hack and slash game, You can't just wander aimlessly around the world being random like you can on WoW. I wouldn't call it an MMORPG at all.
