Villain mechanic on Garen
I'm hoping either a mod or someone who has tested Garen on the PBE can shed some light on my question, below. The new passive on Demacian Justice (R) reads: "The enemy champion with the most recent kills is the Villain." My concern is, in the middle of a teamfight, Garen will be chasing down a villain and just before he ults, someone else on the enemy team gets a kill and the Villain switches. I imagine this sort of thing is likely to happen all the time.
My question is: will there be a brief lockout between when the Villain switches, or is immediate? If immediate, can one of the devs comment on whether a "lockout" period will be tested before Garen is shipped out to live?
Thanks for responses.
