The franchise would have been better if we continued d3.
D4 is essentially a d3 reskin with less qol, less features , less monsters, and a worse skill and item system. Seeing the snippets of the cancelled d3 xpacs added in as seasons, it is clear the game had a cohesive vision and was hitting its stride. Only to be cut short by execs.
Since then we had a 10 year hiatus and are now left with a cash shop with a game stapled into it. Just look at the quality difference between ROS and VOH, it isn't even close.
Continued development on D2R also would be preferable.
