Yea I take serious issue with the fact that we can not convince Zevlor the leader of a group that charged into the hells (The Hellriders) to fight some goblins so they can get to Baldur's Gate is a bit ridiculous.
I didnt even consider that part, i just forgot it. He even fights in the attack on the gates. Even so its impossible all people who turned into Tieflings were all scribes and traders and other non fighting material. And we have a small talk with those three arguing should they stay or should they go.
Just realized that Wyll is suspicious because either he did not get on the Nautiloid or I am missing something I hope this was not a continuity error that is pretty embarrassing.
Im currently considering that all companions introductions were just placeholder implementation, because - i think to myself, surely the eventual full version cant be that bad. Surely no one would think this is how you introduce companions. And its really easy to slightly change how each is introduced to achieve much better overall quality of the start of the game - and also make the companions look like complete fools right at the start.
Wyll is also from that exact area of the game world, which additionally strains the suspension of disbelief. He sure managed to reinstall himself into the druid grove really quickly after being abducted, implanted, sent through a chase through other planes, then hell, got back to the same place on the whole Faerun to crash into and jump back into being a teacher for Tieflings...
I did suggest an easy adjustment to the intro tutorial that would smooth that issue over and provide a believable excuse why the Nautiloid returned to that exact spot - while at the same time removing the unfortunate scene of Githyanaki listening to Mindflayers orders and doing what it tells her to do. While at the same time having no idea how the Nautiloid transponder really works or which tentacles go where and do what.
On the other hand it seems im the only one that even noticed that "small detail" so the studio can pat their own backs and say "Nah, the players liked it, nobody else complained about it, who is that guy anyway, its not like we are paying him at all... lets keep it as it is!"
Otherwise yea I agree with what you're saying, the tieflings need more options, the shadow druids need more options and the solutions need to make more sense in the context of the greater story.

btw, surely its obvious i dont suggest a full rewrite. Thats the whole point.
There is a lot of things to cover up and improve but its basically just adjusting what is already there.
