Simply putting it, do you think having more actions during a turn would improve the gameplay and overall fun of BG3? Hence a very simple fix that could go a long way.
I don't think so, depending why you consider it could improve the gameplay.
More action points for the players and ennemies won't solve anything if we're talking about the speed of combats.
Discussions about the implementation of the rules aside, the only solution I see for more fluent and more enjoyable combats is to increase the party size.
At the moment I'm trying a playthrough with 6 companions and it's way more fun. I have many things to do and everything is more fluent. I HAVE more actions during a round but I'm not breaking the rules even more.
Of course it's way more easier... And it's probably too easy but the difficulty of the game isn't especially a matter of number of ennemies/companions.
- Increased party size = more action during 1 round - Better implementation of the rules = better balance - Well balanced custom mechanics (>< Larian's homebrew) = better control of our %to hit.
Want something more difficult ? Just improve ennemie's damages and/or AC a bit.
