Yeah. The funny thing about humans is that they find it hard to adjust to something worse then what they are used to.
As I see it.
Negatives: -potential for exploits, allowing character not in combat to move far further then they should be, and avoid enemies vision cones easier due to them being frozen in time -unimmersive - with turn-based combat signifying multiple characters in an area engaging in a skirmish, it is jarring for some characters to not abide by the same rules -hassle of checking who did, and didn't engage in combat -adding multple characters to the encounter one by one feels bad to do - transition is bombasting and having the combat cue play out and having initiatinve UI rollout 4 times in a row, is just not a good experience
Benefit: - In multiplayer you won't be pulled into combat by a coop player whom you don't have control over
And as I don't plan to play in multiplayer, and if I do it will be will folks I know, the benefit doesn't come anywhere close to making up for the nagatives.
