As a Heimer player Myself (He's my main with a 3:1 Win, lose ratio) i'm happy to see the granade nerf. (8 second cd was fine tho)
Other than that... my chosen Master yi skin will be adorable.
Pantheon is getting changed little by little... the spearshot nerf was a bit too much if you ask me.
About people calling Shaco OP... he's not OP he needs a rework, seriouslly i don't know what the **** was wrong with the employee that designed a spell that has a blink, invisivility bonus damage? wow... Riot should rework it on a Dota Skill called Blink Strike (the rikimaru one so it has synergy with Shaco's innate)
Akali buff = Good
People complaining about Kassadin: He got buffed and you can't even realise how powerfull he'll be against chars with short mana pools. If you guys never played DOTA there was a Hero (champion), called Magina, his role was to destroy casters by burning mana, having a great magic resistanse and Flashing out. Kassadin on the other hand has 50 Armor Pen (wich destroy casters), A slow, A silence. Yeah you won't build him on AP but trust me... this will work out.
Bug Fix: FINALLY... still there are a lot you guys need to work on.
New Champion: We'll see, theorycrafting doesn't really work on something we never saw/test.
No champion remakes: Nunu, Evelynn Malphite? I'd add Dr. Mundo to this list... he just got destroyed this last 2 patches.
Still waiting for buffs to this characters: Malphite, Gangplank, Tryndamere, Olaf, Nunu, Eve.
Oh one more thing (and sory about this being too long)... with the cleanse nerf There's no better champion than MordeKaiser this patch. Ult + Ignite is preety much a "Demacian Justice + Summon tibbers"... without the damage from the summon and the Sunfire thingy.
