Hey, @Stoneduelist, it seems like the new momentum-based movement is not set in stone and Funcom is open to changing it. I would encourage you to leave your feedback in the official feedback thread, so they’ll have an additional data point:
Unfortunately, I don’t think anything will happen to help with that. Funcom has made these new changes specifically to stop people from always being able to run away from combat once it started.
The best you can hope for is to avoid fights in the first place or to get used to committing to a fight until you’re able to escape.
I do hope you reconsider. There are new tactics available and new ways of doing things. Maybe if you give it a try, you might find some that you enjoy.
