Personal thoughts on how I would change the Sorcery Tree plus a few other runes..

Personal opinions: Slight buff to Nullifying Orb ( Bone Plating has a lower cooldown and it reduces more damage.. ) Absolute Focus gives adaptive AP/AD when above 50% health and the bonus is reduced based on missing health. Transcendence grant its 10% CDR bonus earlier based on takedowns and assists like Magical Footwear. Riot spoke about making Celerity give movement speed on ability cast or in combat, I would prefer just buffing Absolute Focus and Transcendence instead. Ultimate Hat changed to Ultimate Hunter and moved beside Ingenious Hunter/Ravenous Hunter/Relentless Hunter like on PBE.

Celerity, Nimbus Cloak and Waterwalking placed side by side since they all relate to movement speed. Waterwalking has its old passive removed and now grants a small amount of movement speed based on duration in combat or whenever you use abilities, up to 5%?

Transcendence and Manaflow Band moved and placed alongside Gathering Storm because all these runes have to do with scaling into late game.

Absolute Focus is placed into a trio that grant bonuses based on missing health: Absolute Focus gives adaptive AP/AD when above 50% maximum health, reduced by missing health. Absolute Resolve gives adaptive AP/AD when below 40% maximum health. Nullifying Orb cooldown reduced to 45 seconds.

Scorch gets tossed into wherever it would be most contested.

New Sorcery Tree: Keystones - Aery/Arcane Comet/Phase Rush Absolute Focus/Absolute Resolve/Nullifying Orb/Scorch <- runes based on percent health Celerity/Nimbus Cloak/Waterwalking <- your movement speed runes Transcendence/Manaflow Band/Gathering Storm <- your late game runes
