Just because BG1/2 did some things badly, is really no excuse for BG3 to do likewise, surely? 5E rules are vastly different from AD&D or even 3E, and 5E has an entirely different design philosophy. I really think that needs to be respected...if Larian are going to call it a 5E game. There are two huge threads on this, at least, so it is a big deal for many people. I have no pronlems with the story, setting or calling it BG3 - but I want an authentic D&D (5E) experience. At the moment, it is quite far from that, and eminently 'cheesable'.
and all I want to point out is that using BG1 and 2 as good examples of implementation of RAW is willful nostalgia with no investigation of how the rules are actually implemented in BG1 and 2 and so doesn't hold water as an argument for RAW in 5E, it makes no judgement on how BG3 should implement 5E rules, just that there are much better ways to approach the flaws in BG3 than pointing to rules as implemented in BG1 and 2
