the people that don't want to play DU shouldn't be worried since all they stripped from DU is the things they didn't want to see anyway so no harm no foul. Again, worst case scenario.
This is where I'd have to disagree.
By all indications whatever Larian had planned for Tav in EA was much more of a slow buildup, much like the Bhaalspawn of BG I+II. I think I would be much more onboard with that as a storyline for our custom characters, because I never felt like those Bhaalspawn dreams dictated my behaviour. Heck, even Elminster himself shows up to remind you not to let your parentage dictate your destiny. DU feels very much like it could 'take the wheel' from our characters, like Lohse from DOS2, but on a greater scale.
The EA dreams were also more ambiguous in their evil. The bloodlust is concerning, but it also serves as almost a feral instinct that lashes out at the extremely suspicious Daisy.
But there's still the valid question of what, if anything the Bhaal-related plotline Tav was getting has been replaced with. If the answer is 'nothing' than I have to feel like that's a major letdown, since one of the huge draws for games like this is the custom character, and that beign the weakest link would be a real bummer.
