Do you honestly think that by the time its ripe for release, that it will still have most, if not all of these ''problems'' ? The remainder of nitpicky issues will be easily and most probably solved by a modder with the same gripes as you. We have an active and hardworking mod community already, check the Discord, they're working their butts off with what they got.
Mods are not in ANY way an excuse for problems with a game. A game should be judged on its own merits/how it is out-of-the-box, mods have nothing to do with it.
If your statement were true in any sense then in comparison most of Bethesda's games would be crashing dumpsterfires, with no redeeming qualities about them (and that they are most certainly not, well... at least until they did what they did to Fallout

).
I'm all for some of the changes needed that were pointed out in this thread, but some just seem like wishful thinking when you look at things from a game development perspective and as such, forgive me if I'm wrong, they are best left to modders. Anyone who cares about D&D will personalize their experience in any way possible, so yeah, I have no worries about it.
If a problem is simple enough to fix that a modder without full access to the code can deal with it, that should be all the more incentive for them to fix it, as paradoxical as that may sound.
All in due time friend. I understand what you're trying to say, but some of the talking points here have been strewn all across these forums in many forms and ideas over the past year, to say Larian hasn't got them on their radar would be silly. The things left unchanged or not even recognized is bound to be solved by the community.
