What Facts / Numbers do you have to backup this statement.
What you see as flaws , players might see as innovation its completely subject to a matter of opinion.
So you think its bad , I think its fantastic. Again subject to opinion not FACT at all.
You have made it subjectively clear you dont play D3 anymore and thing personally the game is bad. I have played D3 since day 1 and think its amazing.
Your concerns are limited to yourself and a handful of forum posters. Lets D4 be D4 not anything like D1/D2 or D3.
The right community to listen to is the Playerbase thats going to Play it . That more then likely contains people who are playing D3 currently just so you know. Just cause someone likes D2 or D3 or D1 or POE doesnt make there feedback any less valid or incorrect. Feedback is Feedback
