Sorry for not replying sooner.
The reason I stopped playing dos 2 were as follows: After a while when you become powerful getting into a battle was a headache since you are forced into turned based mode.
For me it all comes to efficiency, in pathfinder the same encounter that took me less then 20 seconds
in real time mode, in turn base took me 2 or 3 minutes.
They could have add fast turn base mode like in max 1/2 or like it is in fallout tactics.

Baldur's Gate 3 has both real-time and turn-based gameplay. A great majority of the game is played in real time (although the human player may voluntarily switch out of it), which is in effect while one is exploring, traveling, and generally doing most things. The principal exception is during combat—the game switches to turn-based play for the duration of the combat (although members of the human player's party can make some kinds of attacks while remaining undetected, and as long as the enemy has not officially engaged in combat with the player, real-time gameplay will continue). You can choose to activate turn-based movement whenever you'd like, and its finer control mechanism can be very useful when navigating perilous situations, such as trying to sneak past a sentry.

Most of the time, Baldur's Gate 3 is played in real time; during combat, the game switches to turn-based movement, and you stay in that mode during the duration of that battle.

I dont think you actually speak about storytelling because storytelling as such cant be improved.

One cant actually have better storytelling than, for example, the bible, or Shakespeare, or whatever other such source you fancy.

The storytelling of BG3 is okayish. But I miss the goody two shoes characters.

I was wary at first too. I thought I prefer real time with pause, pillars of eternity being a favorite and I had trouble getting into both DoS 1 and 2. However, watching part of an EA playthrough (specifically https://www.youtube.com/watch?v=HyhoHEuVR6k) swayed me and it turned out great. IMHO, BG3 is more dissimilar to DoS 1 and 2 than similar. I previously posted a lengthy comparison: https://www.gog.com/forum/baldurs_gate_3/bg3_success_far_exceeds_larians_expectations

To address your specific points:

1 and 2: combat encounters are less of a slog in BG3. Due to difficulty, flexibility and the more interesting abilities from DnD 5e vs DoS. Larian has done a great job of ensuring that most if not all abilities are useful at some point or rather. There are far, far more options than the DoS games. There is also way more meat in the rest of the game that combat doesn't dominate the experience in the same way it did for DoS.

3: reiterating the above, Larian has done such a good job of offering situations where so many of your characters' abilities are useful. A highlight for me, pun intended, was that I didn't think a spell like Daylight would see much use but there's a lengthy section of the game where it's absolute gold. I have the impression they tried hard to ensure every ability they put in the game is useful and not just included because it's in the DnD handbook.

I should say, though, what I look for in a CRPG is the whole package of story, characters, lore, exploration and combat. If you're only after one or a few of those, you may have a worse experience.
