We can already see the changes Larian had to make, goblins have 3 times the hp and half the AC, to accommodate surfaces, and to accommodate their ridiculous height 3:1 advantage system
They're going to have to rebalance concentration as a result as well, which will rebalance concentration spells, which will...
this is just going to be a spiral of them gutting the system they were given to use, and it's going to be unrecognizable by launch (battles already feel more like Divinity than D&D, the game really wants you to just shit fire everywhere and burn your enemies out)
