I agree with OP. This game has its moments but the entire loot system is hopelessly bad. However I don't think fix-seed is the solution. I think allowing save-scamming is already the best compromise there is.
...
The current save-scamming approach, I suspect, is just a compromise to make this mess work, and it sorta did, at least for the current beta. Like "we can't be bothered to tailor rewards to your own preference or the enemies' own characteristics, but you're welcome to try reloading to get a semi-reasonable reward for yourself." If you're gonna make it fix seed, might as well just make it fixed result and a pre-determined progression route.
Yeah, I can agree with the heart of your statement. There's a concept that some of the people objecting to this thread seem to be missing. When a developer worth his salt comes across a complaint, they don't just disagree and dismiss it. They generally try to figure out what's causing the concern in the first place.
There's a philosophy that exists within the game industry that basically implies that it's up to the developer to figure out what the player actually wants when they're asking for something, and that what the player wants may actually be different than what they're asking for.
With a thread like this, a developer might ask themselves
"What's causing players to spend time reloading saved games in front of chests (instead of playing the game) in the first place?". That can lead to a developer taking a look at their reward system, not necessarily a way to prevent save-scumming but looking over loot tables and figuring out if adjustments are needed to make the rewards more appealing, or even creating a discussion internally regarding how rewards are distributed and whether or not that's the best approach. Larian has made multiple adjustments to loot tables in the past months and I'm sure at least part of that is due to our feedback.
Random-player-X might come upon a thread like this and think
"this is just stupid, who cares if I save scum", but at the same time may be the same person saying
"this is stupid" (or even
"this is just stupid, I need to reload and try again") every time they kill a boss and receive absolutely nothing useful as a reward. And they're not seeing the connection. It's incredibly shortsighted to criticize threads where players are bringing up concerns (especially if they seem to be putting a serious effort into it and not just typing
"game need better spellz k thxbye") when first registering their complaint, because whether you agree or not with the problem or the suggested solution, it is never a bad thing to get the developers thinking about whether or not something can be done better.
