It really feels like they took div sin 2 and tried to tweak it to kinda resemble 5e instead of just making a 5e game.
There is a lot of div sin in this game that doesn't need to be in it: - Finding 500 consumable potions/food/scrolls/bombs every 5 feet is just annoying as it clutters your inventory and hotbars. - Having 50 different lootable bookshelves/boxes/vases in every room is also annoying. This is not div sin. We don't have lucky looter. I am fine with some RNG loot to make playthroughs more varied but it is just annoying looting 50 empty book cases in a room. - Explodey barrels and such in many encounters, i get it, you want more clever ways to get through encounters but it shouldnt be so common. why are there a buncha explodey barrels in some crypt some people are robbing? who leaves those there? - as has been mention, jumping in combat is totally OP.
I think a lot of it comes down to them wanting it to be a more action-focused game like div sin 1-2 rather than a more hardcore experience like BG1/2 and stuff like Pathfinder Kingmaker. from an economical standpoint they may choose (or kinda have to) stick with that to turn a big profit... though maybe it would be more profitable if it was a true D&D game?
There is a couple of ways to make it win-win though: 1. Pull a Total War: Three Kingdoms and have two modes of play. Give us the Div Sin mode and the 5E mode. 2. Modders will create the 5E mode.
I hope they go with #1 even though modders would tweak it further I am sure, but I could see them picking #2 since it takes less effort from them. But look at Pathfinder Kingmaker recently putting full turn based mode out years after release after seeing the success of a mod. Turn based mode made that game 10x better than playing it real time. So there are definitely ways to keep fans of 5E and Div sin happy.
