AH! Back from work. Can complain at length now.
I don't remember who it was who mentioned Dragon Age: Origins as Larian's main Bioware influence but it's on point - chaining characters, hotbar, or inventory design, it's all lifted from Bioware mainstream lite-RPGs. That kind of stuff is very much why I am worried if Larian realises what they are working on.
Dragon Age: Origins had very simplified designs like that, because it was a very simple game. There was little to no reason to splt or control your party members. Skills were relatively few and even in most extreme cases they tended to fit on one hotbar, and selection of skills/spells never changed. Choosing a weapon meant choosing an upgrade tree and there was no reason to switch between different types of weapons - only ugrade when stright up better weapon shows up. Outside some story choices DA:O origins was about as interactive as your average jRPG.
DnD 5e, even though it is streamlined from previous editions, doesn't work like that. Especially with additinal features Larian added microcontrol of the charactrers is required. Spell casters gain a large amount of spells that a constantly added/removed from use. Some weapons will be ineffective against certain enemies and require switching.
How Larian designed their control systems and UI suggests that they don't understood those differences when working on the game. Equiping your warrior with melee weapons that do different damage types is not only a legacy feature - it is something Larian should actively encourage, not make difficult. They claim that melee classes aren't interested to play - and yet they prohibit from easy access to more then one set of weapons...
Edit. I watched some videos, and am pretty sure DA:O allows for two loadouts but doesn’t restrict them to one melee/one ranged. So that might be Larian’s original “contribution” to the genre.
For example i never known about Baldur's Gate III. and since i didnt play any before, i would probably not even care ...
(Lets give the audience a moment to imagine how beautifull it would be.)
Not at all - welcome! But I do believe that you don't quite realise yet how good Baldur's Gate3 could be with some changes that you like to fight against:) I hope that you will enjoy BG3 and that it to lead to you the really good stuff out there.
