because besalver skewer is more of a skillshot than the new skewer, means the besalver is prone to whiffing and the dash one is less prone to missing, thats just my theory
That is a good point for skewer 👍🏻 it indicates that this skill needs to be throughly tested before using with any random skill. Also, the continuous damage skills are not working with this. That is a bit weird. Skill description talks about channel skills.
