Not necessarily. I'm imagining it as a sort of Irelia for Order and Zed for Chaos. Rather than explaining deeper I'll just vaguely run over the idea I have.
Main form is order because of its defensive stats or whatever. It's good at keeping you alive. When you run out of Order you need to go for damage so you switch to Chaos for mobility and damage, get the damage off, and switch back to Order in order (lel) to stay alive long enough for a second or third round of Chaos in order to be successful.
While in Chaos, your Chaos bar should be automatically depleting over time (filling up your Order). This should start 2 seconds after changing form and is stopped by damaging enemy champions. This is to prevent the player from HAVING to all in the enemy champion(s) to regain Order (lel yet again) BUT isn't necessary. It all depends on how healthy the kit is. My understanding being that it'll be like Rengar where you can't stack a resource without damaging something. And while I suppose one could go into the jungle for a Raptor buffet I like the idea of waiting out the Order form in order to strike the Chaos form. Thinking back on this after writing ahead I think that both bars should be depleting and, upon reaching 0, should force a transformation.
Champion has 0 MR / Armor
Order: Brand level mobility. MR/Armor is doubled. Gain 1 Order Stack (idk) on damaging an enemy with an ability or auto attack. This stack grants armor/mr per stack. Low stickiness and no real ranged abilities, but I'd like to see something ala a mini Janna ult that could be used to keep order via peeling for someone (including yourself). Could even have a short delay for added counterplay.
Chaos: Lucian level mobility. Walks to charge up ala Statikk Shyv and then can cast the ability. Very sticky but in a grab-release fashion. I'd like to think that champions should be able to "get away" from this "cat" of sorts chasing them down via some sort of trickery or quick reflexes. Any champion should be able to do this. Perhaps whenever one is damaged by Chaos they're given a short burst of movement speed or are launched in a direction that they can choose by quickly clicking (or by default simply ala Condemn if no player action is taken). Don't much care for this iteration, though. I DO like that it CREATES Chaos in fights. By adding Chaos to fights you make things more wild by more or less throwing enemies around (albeit wherever they want to go).
Idk. It's very rough and I think I could figure out a proper kit with enough time. Woke up at 5:30am to mice though so glorious traps have been set and I'm still very tired. Adrenaline's wearing off.
Edit: Just had a thought: What if this is instead made to be a sort of anti-dive champion. Like she/he just curls up to the ADC and pushes enemies away by "pouncing" on them a lot. Similar to Alistar but.. actually that sounds pretty bad. Nevermind. Too tired. xD Alistar with super low CD headbutt = not a good time.
