There very much is a difference, but nothing stops you from doing it on easy mode in a group, so it being harder to do solo does not mean it is hard to do.
I don’t disagree, it kinda should not exist, but that is the concept behind an endless dungeon.
Agreed, plenty of stuff to nerf there. I am also not talking about when the game had paragon in vanilla, things had already set primates at that point. Combat was better in the first weeks of release.
In a bad game sure. Just shouldn’t aim to make a bad game.
Eh, builds is honestly the main point of an A-RPG.
Now THAT is definitely not the point 
Sure but it is nonetheless not maxed out.
