Pantheon Support > Braum?

I was just checking out the pantheon rework on PBE, and I think his kit would actually be kinda busted in the support role. He has long range poke with his Q, point and click stun to set up plays on his W, his E blocks EVERYTHING, damage and all, and even stops projectiles like Fiddle E making it good to protect your ADC with, and his ultimate will make him a useful roamer.

I'm comparing him with Braum, as they seem quite similar imo. Braum Q is shorter range and slower and less damage (except early on), but in return it gives a guaranteed slow and it's wider. Panth Q is longer range and faster, but slightly thinner and only slows on empowered one. W provides Braum with more utility and a bit more mobility, but panth W sets up plays, does a bit of damage, and stuns targets. E is essentially the same, but pantheon just moves a bit slower while moving sideways and backwards, but in return he does damage while holding his shield AND it blocks ALL incoming damage, not just reducing it. His empowered E lasts just as long as Braum E, and I the width of it is larger too. The only advantage Braum has to Pantheon imo is being tankier by build, and providing more CC with ultimate and passive. Pantheon does a lot more damage, however, and is like a pyke but with more utility.

Would pantheon support be viable? Even now, although rare, I see pantheon supports as well, just because he does insane poke and point and click stun, as well as being able to tower dive and set up kills for ADC. But now it's 10x better, with longer range poke and an even stronger Braum E. Just curious if anyone else came to the conclusion on if he can be played support/actually tried it out on pbe (I played panth but not support).
