We are going to try and simplify it for those who don’t want to take the time to read the whole
thing and worry about numbers. If you are looking for in depth analysis, we suggest you look at the link above or find another post about it.

Corki

● Big change to q now longer instant damage, now “lobs” through the air, and they increased the range

● E now costs less mana

● R AD ratio increased

Overall probably a buff, depends on how hard the new q is to hit

Gragas

● Q Less range but can be exploded quicker

● E now does full damage to every target, and gets cool down reduction if he hits something with it.  Changes playstyle a bit, doesn’t seem like he will stay at about the same strength

Morgana

● R now shows enemies the leash radius

Small nerf shouldn’t change much

Nasus

● Reduced passive lifesteal

Nerf, better chance to shut him down early. Still seems really strong.

Nautilus

● Passive stun duration increased at higher levels

Buff, not huge, still about same strength.

Nidalee

● Q overall does less damage at closer range, still does same damage at max range.

● W debuff time reduced

Nerf, makes Nidalee harder to play, reduced dueling potential, late game poke will still be there.

Nunu

● Q Less damage and healing early but lower cd

Keeping him balanced with upcoming changes to smite, no real change in power

Sivir

● Q damage taken away early, more damage late.

Overall just a shift in power, weaker early game stronger late game.

Vayne

● Condemn changed.  Should only affect the top level vayne players.

Nerf, but will probably go unnoticed to everyone thats not at the top of the ladder for Vayne players.

Janna

● Passive no longer global, more movespeed for champions closer.

● Q now must be channeled for full duration in order to do max damage

● W and E now scale with Janna’s ap

Implementing some of the support changes riot has been talking about, passive and Q nerfed while W and E are buffed late game.

Leona

● W Scales with bonus armor and mr instead of flat values

More support changes, Leona now scales better with gold

Lulu

● Added ap ratio to passive

● Q, W now scale with AP

● E ap ratio reduced

Overall nerf but scales better with AP

Sona

A lot of small changes, power being moved around

Should scale better with gold, overall keeping the same power

Soraka

Added scaling and reduced damage from most abilities.

Overall should be a buff, and scales better with gold

Taric

Reduced scaling with ap added more scaling off tankyness

Buffed when building tanky.

We will be releasing a Simplified Item Rundown tomorrow for Patch 3.14, look out for it!
