Add a vertical aspect brings camera issues. First release of Original sin had even fixed camera, so player could focus on gameplay. Now, the player focus camera movement. That is unfortunate. Battle is slow/boring due to a player must check all possible camera angles. Cant imagine play this in 4 coop. Game of waiting. I hope you find out how to fix it (remove camera fiddling) and come back gameplay on the throne.
Original has +++ cartoonish art style - specific recognizable style. Trademark style. Now it looks like any average asian MOBA on the market. Gutted, without balls. Dont understand why you remove the specific style. Its like Simpsons start to use 16M colors and white people.
Simplified AP - unique combat which previusly allowed to pass fraction of AP to another turn is gutted. Now 3 AP per turn removes smoothnes of previous system. I could understand to difficulty some people to count to 20 so lets streamline to 3. On the other side, cant understand why still keep hundreds of HP point. It could be more stream-line to hit for 5HP than 50HP isnt it? Why do I need 2486 HP ? Would I be a looser to have 2468 ? How the people who need 3 AP to be able to play could handle such high numbers ?
Skill classes are more and more same. Ranger or fighter doesnt matter - both are filled with ranged AOE. Stupid. Oh wait, movement costs AP so ranged AOE makes sense ... That is stupid at the best.
Even i watched video 2 times I didnt get meaning of those new 2 bars above the HP bar.
Your previous games, Dragon commander suffered by same mad presentation. Put everything to anything, boil it up, mash it down, put a ton of spice. Result -> awful chaos.
Sven, said that DOS original aim was a small game a side project but dragon commander the big one. Maby you could re-think what was the rootcause of DOS success over the Dr.Commander.
I think there is a lot of work waiting. I hope you manage it it somehow :-/
