The only class that needs tweaking is druid and It might not even be that much since the class mechanic requires world exploration.

Your first and second point can literally be fixed so quickly and finding those flaws were the point of the beta. You don’t need to delay a game just because one class movement skills moves you the wrong amount of distance.

And your last point is literally just wrong. The beta deliberately limited your exploration to just act one. You’ll get to explore the other 90% of the world on release when you aren’t playing a beta.

And with dungeons again you only played what they wanted to show you. We are going to get different dungeons in the later acts. Realistically any game that has dungeons only has 5-10 unique dungeons and if you believe the “over 100 unique dungeons” brag every company says then idk what tell you other than compare the dungeons to any ARPG and count how many unique dungeons there are
