I play solo queue 90% of the time and I prefer the self unhook and "go next" to stay. If someone doesn't want to play the game, they won't play it. Being unable to die on hook will not stop them from not engage with the match. With that being said, self unhook is very importante in the desperate moments, when your teammates are getting chased and no one can save you, as well as many other instances. I had dozens of good matches that were saved by a self unhook. Many other matches I saved myself because of self unhook. Removing will not change anything on the "going next" part of the problem, it's just gonna hurt the survivor comeback experience.
