Watching Sensuki's latest video and how he describes all the ways to fight disengagement and I come away with the mindset that it just adds more tactical decisions to the gameplay.
I don't believe it adds any decisions. By default without engagement the same decisions exist, it's just that there is no penalty for disengaging. All disengagement attacks do is penalize you for one certain action (moving while engaged) which actually makes that option not very viable compared to the other options available.
The IE mod removes the disengagement attacks but keeps the AI part of the system, and IMO it's a lot better because it doesn't punish movement in combat. Positioning is still important and you now have the option to re-configure your frontline without penalty.
The things that break engagement (interrupts, disables, movement abilities) are all just as good as they were before, IMO.
I deliberately tried to keep my opinion on the system in the video pretty muted so people could make up their own minds, and tried to clearly explain how to play with the system.
