it was very contextual in origins that means , if there's no platform to side/back ejects to bayek won't do it, in older games you can manually side/back ejects anywhere even if there's no platform to reach, this gives extra complexity to the parkour as players can side eject and then grab ledge before falling to their death or back eject into a ledge grab into another side eject etc, this created even more speed and momentum that was fun and not so difficult to learn moreso, casual players can avoid this while maintaining a fun experience.
