Garen should not instantly designate a new villain when the previous one is killed

Title. I know he isn't exactly OP right now, but if he gets some buffs or eases into the meta I wanted to point this out. It's kinda bullshit how he can potentially kill one guy, then get right to dealing true damage to the next one and the next one. I've actually won 1v3s because of this. I think there should at least be a 10 second grace period in between picking new villains. Give compensation buffs if needed, I just don't think this aspect is fair.
