I agree with pretty much all of what you wrote. That is a very well done set of critics for sure.
Considering that, even though I do disagree with some very specific things, Larian should most certainly take a look at this.
I do have one major question though, what exactly do you mean with this?
"Risk Management is gone, RNG remains.
Accuracy, Ability Success, and Saving Throws are either gone or redundant now. Despite this, RNG elements still plague the game with Critical Hits, randomly generated gear and loot, and various random % effects on generated equipment, amongst other examples. There is no element of chance one can strategize around, but plenty of dice rolled."
This whole paragraph is very confusing and isn't quite clear, for a few reasons.
1 - Yes, risk management is gone, but less RNG has nothing to do with that, if anything no RNG means less risk to manage because there are less variables.
2 - RNG on combat and outside of combat are 2 completely different issues, split those up, maybe.
3 - At the same time you state RNG still "plague"s the game, there is a complaint that there is "no element of chance one can strategize around". While I agree that there is little to no element of strategy on the game's current combat, I strongly disagree that it is in any way related to the level of RNG (X-COM has several degrees more of RNG than Divinity does and saying the former has less elements to strategize around is laughable).
So in conclusion, do you mean that you want more RNG elements and the return of accuracy and saving throws (I doubt Larian would ever do this considering the direction the game was taken on), or do you mean that you want the ones that are currently there to be removed?
Personally I think that this is mainly a complaint about a collateral effect, and not a problem in itself. If the low ammount of RNG that is in the game right now was removed the game would be even more of a cakewalk, that is just not the problem. The real problem, is that there is nothing to strategize around, there is always a very clear best strategy without any real risk to it.
As for the loot, I don't think anyone really disagrees that it is currently one of the weakest parts of the game.
