As a preamble and disclaimer, I'm not really that invested in the combat and strategic aspects of BG3. It comes well below basic playability, and below immersion, in my list of priorities. It's not that I don't love good combat systems and strategy games, it's just that I have long stopped hoping that this is something Larian can deliver. With this out of the way
And i would like to know how do you imagine Larian should deal with this on level 5 ...
Should we be able to use two Special Attacks in single round?
Should we be able to use our Special Attack + Regular Attack?
Should we be able to use our Regular Attacks only, in order to profit from Extra Attack feature?
I think that, when making 2 Attacks as part of the Attack Action (with a martial character, at level 5 and above), we should be able to choose, for each Attack, whether
- it's a Regular Attack,
- it's a Weapon-induced Special Attack,
- it's a Shove,
- it's a Sneak Attack,
- it's a Smite,
- ...
Obviously, that means that Larian's current implementation of Shove or Sneak Attack as being the whole Action, instead of just properties of your Attacks, should go away.
(And as Demoulius recalled above, some of the Weapon-induced Special Attacks that Larian introduced (like the circular/sweeping strike) are, very unfortunately, taken from the list of exclusive things that the Battle Master subclass can do, and thus devaluing that sublass. Just like Hide-as-a-Bonus-Action is stolen from Rogues. Sadly, there's a pattern here.)
