Plo koon doesnt need that much work to become viable. With the right speed and potency he could make a clone team viable quickly. QJ as leader would cause PK to act quickly and boost clone speed with a followup clone sergeant to turn meter down, or an effective offense down to prevent one shotting. If offense down could nullify oneshots it could bring an alternative to the current meta and make attackers forced to survive through the debuff and a chance to have a tank taunt. It would be nice to see a team like QJ PK CS Fives(slow to mitigate more damage) and a tank with taunt work. Even if it might rely on QJ for speed and damage it would still open another fun possibility. The big thing here is also making defense up effective. If a tank could actually do its job with the buff and a taunt more options would competively be available.
