I’m still new to Medium so I’m not certain if this is the right way to reply to your response but here goes :P
I agree that in that case, it kind of falls off, but at the same time, it doesn’t need to be good in EVERY situation. Now that I think of it though, maybe a way to cover that vulnerability would be to make it so while his E is active, the “max” speed boost gained from being close would be applied to all ranges.
I actually thought about the change more and I’m more concerned for lower levels of play. Lucios who try to wall-ride to be a nuisance or even flank the enemy team might start getting flamed to get back to the team to give others heals. I’m all for teamwork/coordination, but the change kinda restricts Lucios to a specific playstyle in order to actually contribute.
