Saw a comment on the Brand dev corner, thought I would share the idea here

NOT my idea, but I like it.

Swap his R and his W, but not as is.

Make Pyroclasm into a small-ish ball of fire that bounces around, prioritizing ablaze targets.

Make Pillar of Flame into something like a delayed Spirit Fire, but on steroids and obviously minus the armor pen. After a delay (would have to be longer than now), explode a target area (think Ziggs R size) into a pillar of flame for X seconds, dealing X damage to enemies in the initial blast and half that every second to enemies who remain inside.

Also, replace his stun with a Fear that causes the target to run around in circles (AAHHHHH WTF I'M ON FIRE)
