@ Maximuus - I agree about not having to limit yourself. And you will know from my posts (I have agreed with many of yours) I have been very unhappy by Larian's 5e implementation. But AC is important - and it should be where it is supposed to be to have balanced 5e encounters. Being able to get a 32 AC , as some people are people have shown, is just game breakingly high and almost nothing can hit you. Personally, I don't see the fun in that, especially if you know its based on a broken/poor implementation.
Of course, I agree that many other things are more problematic in general (the list is long...)
I am still waiting for 'core' mode. I may try play with some mods, but I *resent* having to do that in a game that was supposed to be the 'definitive 5e experience'.
In fact, I don't know when I will replay BG3 - I'm quite tired of it now and I've moved onto other things (Cyberpunk 2077 atm). I'm now looking forward to W40K: rogue trader. That at least will follow the rules.
I still kind of vicariously lurk here in the hope that something will change to improve the mechanics of the game.
