Idea for Brand: make his spells interact with himself
I mean, his whole point is that he uses spells to make enemies burning and using other spells on burning enemies gives bonus effects.
And... technically he is burning the entire time, so why not involve him with this?
R - Can now bounce of Brand, the next hit deals bonus damage. (Would make him a strong duelist tho, might have to get tweaked) E - Can now be self cast, causing a ring of fire to erupt from Brand. Not just sparks, think of Leona's shield-explosion. W - Not exactly sure on this, but what about some health/mana restore if you fire yourself up? Or a temporary flame aura? I'm not sure about this.
And Q... well, you can not really hit yourself with that unless you use flash...
