Ill explain why Iv done these.

Fizz isnt being overnerfed, he is an assassin not a mage. His job is to more or less, cancel out a soft target, and any soft target he can get at that. His Q applies on hit's, his AD, and a base plus a AP ratio. At the moment this can be upwards of 1200 damage on just his Q prior to reductions. The damage reducitons are to let him still execute targets after they get hit with his R, but not just hand him free damage during the laning phase and be (what he is right now) the Darius of mid lane. His mobility is hit simply because he doesnt need a free gap closer + Zhonyas on a 5 second cooldown. He is going to purchase CDR to allow for more R's more Q's and more E's. The change makes him purchase CDR if he wants to spam E, rather than just getting it around level 11 for nearly free. Assassins dont need to rotate through spells to accomplish their goal, and he still does his job, but only when he is ganking or TRYING to assassinate someone. Not just at level 6 picking up free kills on anything soft that walks into his lane. Similar to Katarina, he does his job, but he isnt a free win vs soft targets now. (Riot has actually nerfed the shit out of W's active in this newest patch for the same reason I am reducing the passive damage, too much AA damage and Q benefit on a caster.)

Gragas is a fairly common pick right now since he is above Elise, Nocturne, Tryndamere and is nearly tied with Nami for play rates. All 4 of these are top tier picks at the moment. He's actually borderline overpowered, similar to Zed, he isnt COMPLETELY OP but he is close. His mobility is much too high on his E, and his sustain in lane without any kind of purchases made towards it was much to high considering he already spams abilities as it is. This makes him more fight oriented instead of just push based free farming till 6. It will pressure you into being an aggressive laner and make use of his passive to be a play maker. His ultiamte was just too high considering he has low CD's on everything, will have stronger AA's, and is tanky. His R isnt for damage alone, mostly for the displacement, the damage is just a REALLY nice bonus.

Kassadin was never meant to be a strong laner, Riot has even said this themselves and thats the basis for why they want to turn him into more of a teamfight based champion with his R changes. And the massive base damage reduction to his Q is because he isnt meant to dominate in lane AND dominate around the map. He has to choose one or the other. And his Q will still deal alot of damage, but he wont be able to push you out with Q alone and then just all in you 2 times at 6 or 7 for free gold. Early on AP doesnt give you damage, bases and Penetration does. With as strong of a combined burst as he's got, harassment was his means of winning lane. He shouldnt be doing that when he should be roaming instead. (By the way, Riot is nerfing Q's scaling damage more than I am. I am nerfing its early damage) He, like Fizz, is an assassin and a roamer. He shouldnt be dominating lane. The changes to his R here are actually some of the first ideas Riot had to change him, back during the 3.12 PBE rotations. I just modified them a bit. These honestly arent very hard nerfs, the only thing nerfed was his Q and his E I  touched slightly. Removal of the AS was because he had no reason to have a 1% indefinite stack of AS when hes a caster, and his passive gives enough effective MR. Whole point was to focus his R damage into his main source of killing, rather than a ranged burst with R augmenting it.

The buff to Noc Q doesnt really change him too much. It gives him more mobility and presence in ganks, but he cant keep you nearby nearly as effectively now due to the big range nerfs to E. Its not really compensation as it is making him a high pressure jungler whereas hes currently low pressure like Nasus. It changes him to be more Carry like in execution rather than tanking due to him being able to apply more pressure and earn more gold. It will change his playstyle/build more than his actual fighting.

Crippling Dagger is because people dont take ignite for grievous wounds. Ignite is taken for increased kill potential, nothing more. The dagger idea is specifically for grievous wounds. Top laners are the target of this item because Shen, Aatrox, Trynd, Renekton, Nasus, etc are all big because of their high sustain and safe playstyles. In a lane that promotes tankiness over damage right now, trading and continual harass is more important than all in burst damage. Dagger will allow you to trade with them if you arent using a high sustain champ. It also gives a fighting chance vs flask, catalyst, and regen builds on champs like Singed. Also, the item doesnt give full Wounds, only 30%. Executioners is now a kinda expensive upgrade and should only be taken if your going to benefit from having wounds. It will still be niche, but it will make it worth the purchase. It's intended to counter annoying Top laners if you want to use someone that cant deal with them. Its a in-game direct counter, to direct counterpicks.
