Pantheon mini rework

I had a random thought a couple of days ago about pantheon. As an aspect of war he should be more skillful than pressing q until they're low and flash w e q ignite killing them. I figured you could rework his Q into a projectile that hits the first champion it passes through and can hit up to 3 enemy targets. It would be like jhin's e where you can store charges of it (recharge cd 10-15 sec?) and actual cooldown is 4-8 seconds. His ult should be an aoe arena much like kindred's and camille's where all damage in the zone is amplified by 25-50%? and upon entering or if you're already in the zone you can't leave until it ends.(3-6 seconds duration?) Obviously there's some tweaking about numbers to do but I think it is a solid idea for a mini rework. Thoughts? [slayer-pantheon-popcorn]

P.S. Although I do realise that damage is quite high in the game I still stick to my guns on this one.
