Well, I understand his point of vue. Divinity 2 was a great change, we moved from an old school isometric hack'n slash to a 3D hack'n slash. and now we move to a turned base strategy game. I can understand that some persons might not like this évolution.
For my part I prefer hack'n slash and dynamics games, but I have experience so far sevrals kind of other games and sevrals really good turned based rpg such as golden sun (that I recommend to every one that loves turn based games and fantasy), grandia 2 or other that I cannot remember.
A simple example for those who thinks that it will not be a good game because it is a turn based game : the Final fantasy... who can said that they are shitty games that did not work?! (even if personnally I never finished one of them)
