I swear none of you people have played 5e before or understand why certain spells and features are the way the are.
I agree for some of them. But what about the new players and the inexperienced???
Especially for new players to dnd it would be helpful to have an implementation close to the original rules. Because instead of simply learning dnd by playing the game you learn also the skewed action economy of bg3 (like why does every dual wielder has to have a 3 level dip into Thief? why does haste give another 3 attacks to fighters? also why do I keep ac from shield while using a longbow?) As a new player you think you figured dnd out while in fact you just identified some flawes in the mechanics of bg3.
So yeah, looking forward using that rules as written mod in the next play through. The changes to the bg3 ruleset seem plausible right away even without having played 5e before.
