RIOT's latest patch with the newest addition of the League, Diana. Other interesting changes are for Rumble, Urgot and Cho'Gath amongst others.

I've seen Princess Diana played as a jungler and a mid and she does well in both roles. Her wave clear can be really fast which might make her a viable pick in competitive play for both lanes. More info on the 2nd Banana girl can be found Here.

This patch isn't all about Diana though, RIOT have been reworking their oldest champions and this time they've picked Cho'Gath with some necessary and logical changes. Urgot who was a highly contested pick through the whole year untill the nerfs came around, got reversed a bit. He dropped a lot in popularity but still had his usage, the buffs he got will probably make him a really viable pick again, who knows me might see him a lot in the up coming Regionals. Last but not least one of the most OP champs since the Jayce patch, Rumble, got tuned down. Hopefully making him less of a target in the banning fase.

all the info of the bug fixes, buffs and nerfs can be found in these patch notes:

* League of Legends v1.0.0.144

Diana, Scorn Of The Moon

Crescent Strike
Diana swings her blade to unleash a bolt of lunar energy, afflicting enemies with Moonlight and dealing damage in an arc before exploding.

Pale Cascade
Diana creates three orbiting spheres that detonate on contact with enemies to deal damage in an area. She also gains a temporary shield that absorbs damage. This shield is refreshed if all three spheres detonate.

Moonfall
Diana draws in and slows all nearby enemies.

Lunar Rush (Ultimate)
Diana teleports to an enemy and deals magic damage. Lunar Rush has no cooldown when used to teleport to a target afflicted with Moonlight.

Moonsilver Blade (Passive)
Diana has increased Attack Speed. Every third strike cleaves nearby enemies for additional magic damage
