Hello,

I understand the need of Larian to customize a little the D&D experience according to their taste, it's ok and diverse. There is an issue tho when you mess with the rules of a very refined edition of the most famous RPG on earth, you risk to compromize balance.
The biggest issue which in my opinion is almost a deal breaker on the long term, is copy and paste of the barrels mechanic from Divinity Original Sin 2.

In D&D, and many other pen and paper RPGs, the core of the game is your character (his class, statistics, personality and the choices you take when you level up, prepared spells, etc).
The fact that the game is so pupulated of explosive barrels, acid barrels, flaming surfaces, etc, it's game breaker. It doesn't matter anymore what's your class, where you spent your points, what spells you prepared, all that matters is: "how many barrels I have and how can I make them explode in order to defeat the enemies?"
All tools that can be used to make the combat more diverse are welcome, but the character and its choices must be at the center of the game.

Another issue I have directly connected with the previous higher level issue, is that the splashes are way too big, they last ethernally and the characters, even when the combat is done, keep walking on them at any minimal movement of any other party member. I think that at least out of combat, the autopathing of the party members shoud automatically avoid the splashes, and those should at some point disappear.

At last the UI for spellcasting should be completely revamped. There should be a small openable window (not full screen) in which all yout spells (subdivided by level) are visible, and the ones you prepared are colored (or something similar). As it is right now, it's really not good.

These are just my personal opinions, hopefully my feedback can help more people enjoy the game.
cheers!
