A little late coming back to this, but realised why Bardic Inspiration felt a bit underwhelming compared to table top. It applies to the next role, where as in pen and paper you can see what the role is before deciding to use it. As written each use has a good chance of turning a failure into a success, but in BG3's implementation there's a high chance of it being wasted. It kind of needs smart usage, as simple as it was only used when the degree of failure was within the inspiration dice's range. That would make it better and much closer to how it runs in P&P in practice. I think this feature underperforming is a major factor in why Bard felt a bit meh to me. Even as implemented it can still be strong with the right setup (like pushing through GWM hits along with a spell like Faerie Fire or Hold Person). But it should be a feature that it's a bit easier to get value out of.
Annoyingly I found some bard items while playing a Sorcerer as comparison (Cap of Curing in a chest tucked behind a pillar near Alfira in Druid Grove, Blazer of Benevolence from talking to Volo after rescuing him). The Bless from Whispering Promise doesn't seem to trigger on the Cap's healing which is kind of a pity.
All this things stacking: NO REST LIMITS, no cover system. high ground, bless, archery, Bardic Inspiration, items and how easy you get advantages in bg 3 all means you can hit anything anywhere anytime you want... if you have a bard around. IF it worked like in table top it would be even more broken but ok...
