Hmmm I think some companions have been made to seem a bit too important than they were in the original series anyway. I mean Jaheira was likely only popular because you met her so early on in the story. As for humans somehow bridging a 140 year gap, aside from Minsc (who was petrified for 100ish years), would be a bit much. Only way I see edwin making a comeback if he managed to become a Lich or something. I already think two characters from the OG series is enough. And they largely serve the role of: LOOK THE GAME IS CONNECTED TO THE OTHERS!. Mind you if Jim cummings voices Minsc again I will be fine with it.
I'd rather see some more focus being given to how they address some of the more key aspects of the DnD ruleset, such as class restrictions on learning spells from scrolls. Reactions I would like to see something on as well. Not necessarily copy paste from solasta, but in a manner that we have more control over how reactions come into play. Having spells like shield and counter spell are quite useful in engagements with spellcasters and such, so for me 5e without those would be weird.
I mean I guess flying has already been confirmed now I suppose, but I expect it will be more of a traversal method rather than a combat tactic in BG3. I like BG3 for other reasons than I like let's say Solasta, but would love to see a more purist implementation of the ruleset here and there.
I mean 8ish months seems like a lot, but the way time flies these days, it will be August before we know it and I expect a lot of the community is waiting with baited breath on the elephants in the room when it comes to their concerns, and how and if they are being addressed by Larian at this point.
