Low cost cheesy champions (Nice balancing Riot)
These are among the most broken and unlike 
,you don't need to play lots of games since they are cheap.
Here is my list:
No skill shots, passive stuns you for ages,ult has an aura(something that riot should get rid of) also has attack speed and its quite tanky.All of her abilities have quite a decent casting range, with Emphasis on the ult, the casting range of tibbers should be nerfed.
"""""""""Reworked""""""""", i honestly need the weed riot balancing team smokes. Anyways,natural life steal, eternal fear from his E, at a decent MS his ult is the length of the highway to hell, and ww can be tanky , full ad or full AP, and he has dual scaling.Don't really a have to be skilled in order to play him, the only skill shot is his ult, and in mid-late game, he can kill you with his Fear + Q cheese. 450 Ip
Obscene jungle clear, lots of mobility , abuses crits and red smite,outrageous attack speed scaling, when he gets 
, he throws you out of the edge of the world, if you don't feel like building attack speed, you can always go and cram up with lethality. Cheap Talon
A champion that requires lots of """""Skill"""""", set them with W, then E, and then with Q, you will one shot them with one rotation and you will get a shield and some MS so you can peel yourself, the only non-broken part of his kit is his ultimate, scales out of Mana and AP(Mana gives you even more Ap, so you have a second rabadons) ,and most mana items have CDR, so you spam your abilities for centuries.Totally not overloaded..
.....................................................
As a Bonus, here is a champion on the opposite situation.
is a horrible champion, only works as a tank since his only effective AP ability is his E, Despite being a giant fucking yeti, he cant cant seem to Dual scale like, he is only AP and tank..... And riot can't decide the role for him in the game, so he has a inconsistent kit, he is really situational and niche, the only redeeming factor is his ult that can clutch sometimes. And if you try to make him relevant again as a supp with something new, you will get banned. While you are fine if you try AP 
in mid lane with scaling mana runes.
: They jump on you, get off super easy CC harass and plenty of empowered auto + attack speed roid bringer making them even more scary when they show up on URF mode.
: They can jump across the map and butt guard a squishie and make it effectively a pain in the arse to deal with them whether its Shen taunting you and able to pull you across a lane straight into his butt buddy to nuke ya, Tahm eating you or his ally to deny you a chance to kill them or drag you out of a tower or just being plain tank annoyances.
: Lethality ADC build styling, High damage poke, Armor shred poking, Tank busting. Basically champions who i bet every single one of them have 1 or 2 branches of Lethality runes and then basically making 'good use' of that early 5~10 flat armor pen from the 60% lethality they got stacked up to just snowball you to death and once they are fed they are just annoying monsters if you can't effectively one shot them, high CC them or negate the damage nuke spaz outs they bring.
: The blooming annoyance who can fk the tempo of a team fight with one R press, run around the map to troll you with surprise flank/dmg pokes like he's trying to make a "Doombot Singed" look bad and he can easily go tank mix easily in the process and still damage harass relatively well.
: Can they seriously just remove the damage on his R? The heal burst on the R thru his AP build is just so ridiculous to where he could full heal thru 80% damage taken, jump across a large section of the map in the process and still damage nuke anyone in the field. I've ranted it so many times but he's less of a "Assassin" and more of a "Troll who has a stick made of nuclear materials that might as well make anything it hit explode if it ain't a very sizable tank."
