Having completed a couple play throughs, I think Larian is on the right track with the game. Granted I hate the fact that eating for healing is a thing or that enemies instantly heal out of combat. I never played the DOS games, so I don’t know how much course correcting Larian does based on community feedback. I think it is important that this feedback keeps hitting the various forums Larian monitors. Larian is likely to change certain things if they are clearly unpopular. Reading through the forums over the last several days, it does seem like there is some consensus for parring down some of the heavier arcade elements of the game in favor of a stricter adherence to 5e mechanics. At the end of the day, as a community, we have to have realistic expectations. This game is almost certainly based on a highly modified version of their DOS2 engine, and they have a certain formula to building their games. I think he final version of the game will actually be adapted in a way that we will be pleasantly surprised with, but we have to accept that many core elements will not change. I am still enjoying playing EA, but I think we need to be patient with Larian.
For me, with the direction that Larian has gone, and is hellbent on continuing, I doubt I'll even attempt to play the game in full after release if the combat remains centered around height/broken stealth/push/elemental surfaces unless someone puts a mod together to remedy the DOS tropes.
