To be fair POE 1 had too much boring flavour text Josh Swayer even admitted that later in his blog and the issue was fixed in Deadfire. And the full voice acting made reading mostly obsolete luckily Swen announced that all their future games are fully voice acted as well.
If I remember, it was alot like BG2 in that for the bigger dialogue instances, the first couple 'paragraphs' were voiced, but then there was always a good amount of unvoiced text following.
Not that I prefer one over the other, as you're going to read all of the text regardless, if you're into the game. Unless you're playing the game for the 20th time, or you're doing one of those ridiculous speed runs for a youtube channel...
That brings up another issue.. if Larian is putting alot of their eggs into the multiplayer basket... things like reading and spending time in weapons/armor descript's as well as any lore sections included in the game (it's D&D afterall) would be mitigated I'd think, because you'd have party members on comms saying, "Let's GO! C'mon....!" (I don't know, I've never even thought about playing RPG's like this multiplayer).
