Thing is that they based this game on the rules of D&D 5e.
Larian has clearly demonstrated that their vision of D&D 5e is their DOS engine modified to have D&D skins and flavours. We have shove and jump because Larian, not because of anything related to D&D, and the reasoning is "because homebrew rules".
Its not based on DOS, its based on D&D 5e. The changes are homebrew rules taken from DOS. At least thats how i see it.
As i would say "never change a running system". But if you do, you should be aware what the consequences are. Even if its just 2 small things, it completely alters the flow of combat. and for what? Laughs? Our party sadly consists of only 4 people. Insta Death shoves can be a real mood killer.
Larian did not decide to make another Divinity, they decided to go for D&D Baldur's Gate. Set in Faerun on Toril in the Forgotten Realms. So as a long term D&D player and fan i kinda expect adhesion to D&D.
Don't get me wrong, i like the game but this is a change that simply makes no sense. They have their DOS flavor with all the surfaces already. Otherwise they could just have used their own rules and just got the rights for the setting from WotC (not that they had done that).
I would still not like it but would not complain because those mechanics are based in their rules.
And as stated in a lot of places already its not only annyoing but it impacts on other things that do adhere to D&D rules.
