Passive Concept for a Juggernaut/Raid Boss
I've been seing a bunch of threads about Mordekaiser's Movement Speed lately. They reminded me of the fantasy that Mordekaiseer is supposed to fulfill, of a heavy suit of armor that slowly creeps up on you. If you ever let it get too close it just destroys you but you have troubles shaking it because it's a freaking suit of animated armor.
And it gave me an idea: I wonder if it would be worth trying to enforce such a fantasy with a passive effect. One like Jhin's passive but with Movement Speed instead of Attack Speed.
Here is an example:
Creeping Death Juggernaut A has fixed Movement Speed (325 -- 355 based on level) that can only be increased with Boots and by Ability - A. Additional sources of Movement Speed instead increase his Tenacity by X (bonus Movement Speed/650) and Slow Resistance by X (bonus Movement Speed/325).
And then Ability A, a short ranged damaging ability, could give that Juggernaut a short burst of Movement Speed when they've reached their target:
Ability A [...] If Juggernaut A damages an enemy champion he gains 20/30/40/50/60 (+bonus Movement Speed) bonus Movement Speed for 2 seconds.
The rest of the Juggernaut's kit would still have to cover sustain, tankiness and damage of course.
Edit: Alternatively, the Juggernaut's abilities could scale with bonus Movement Speed in other ways. It could lower cooldowns, increase attack speed, increase animation time, projectile speed, or tick rate. It could also increase damage or tankiness, debuff enemies, buff allies, or increase healing. You could do all sorts of stuff with an additional ratio.
Edit2: In retrospect, giving a champion both a lot of Tenacity and Slow Resistance might not be the best idea as it offers little counter play. Tenacity would probably be better for a Juggernaut as it helps them do their jobs when they're already in the fray and helps against being kited, while Slow Resistance might fit more thematically. If one of the two is removed another bonus could be added instead, depending on the champion's kit.
