What would you say exactly is lacking? Can you provide a more detailed bulletin list if possible? Because in my opinion it's already far ahead of D3 launch state.
I mean a lot of these a common criticisms so I’m mostly repeating what’s already been said.
-Early game class balance is off (this will be more of an issue when seasons drop)
-Itemization is underwhelming to say the least. +Skills are a great thing to carry over from D2 though.
-Level scaling/power progression feels off. Ie not satisfying
-Don’t stand in fire mechanics negatively affect melee more than range. It’s fine to have that but don’t let it neuter melee dps constantly.
-Too many small pockets of enemies leading to lots of down time running from group to group
-Too much backtracking in very simplistic dungeons
-Skill trees are a jumbled mess in their current state
-The potion system is a little too gamey for my liking. Will have to see how that system holds up through the course of the game.
-It’s not very clear how certain mechanics work such as berserking and overpower
-UI is a cluttered mess, both on screen and in menus. Too many pop-ups.
-No set gear at launch
-Why are legendaries and uniques so similar in terms of magic properties and affixes?
