Well to be fair, the problem with the champs that you list are that theyre just designed to be unfun. Yas is way to forgiving and rewarding. champions like him make supports obeolete. why would you need a proper support when you already have shield escape windwall gapclose AND aoe CC. Zed is a low interaction champion, no better than statcheck champs, if he has enough dmg to kill you then youre dead, if he doesnt then you will live. how do you counter him? buy zonyas
Gnar is a champion that is designed to play in a lane where most others are melee, so giving him range is by itself a strenght. but on top of that he has a combination of poke escape and slow that makes him literally unfun to lane against. How do you kill a ranged champ with cc? you get on top of them, but not gnar he has a get out of jail free card, he jumps away.
My biggest problem with lol is that they have, since season 4, been saying that they want champions with MORE interactions but the champs that are constantly on the top of the teirlist are the likes of yasou and zed, who are low interaction champs. when you lane as one of them then YOU decide when there will be trading, YOU decide when there will be an all in. IM playing as yas, and my opponent is tryin to trade in lane, NOPE ill just windwall and ill trade when it suits me better. when i have tornado so that he cant answer. should i miss? np he cant trade back, i can dash away, charge it back up and try again.
Playing against champs like them (and riven for example who have no window where you can trade with her) is just so boring. its so onesided.
Zyra on the other hand is a fun champ, she has skillshots that you can dodge(interaction) plants that you can kill, tank or ignore(interaction) she often have to put herself in a tough spot to engage and get her combo off(interaction). She have to deserve her kills, trades, engages, aso. Unlike zed where you, faceroll your keyboard from right to left, or yas where you press R after someone else have engaged, and you suspend multiple ppl, do dmg, get shield and proceed to place your cat on the keyboard.
ANd btw. good players who lane against fiora, they know to walk away so her passive resets. just let that sink in for a while. Her passive, is designed to mark you, BY ITSELF, and if youre UNLUCKY you get marked towards the side that is facing her, so you walk away and then you walk back.
that is LITERALLY the interaction you have with her passive. It marks you BY ITSELF, you WALK AWAY and then repeat. THATS AN ACCTUAL"INTERACTION". But oh no dont let me forget, she follows that up by a short dash, an AUTOAIMED attack that gains some range and then she get a movement speed buff so that you wont be able to interact with her, so that it goes one way. And if you BY GOD play a champ that can trade back then they gave her a parry just to make sure that she will win the trade. FUN!
Back in the day Taric was acctually considered OP because he had a point and click 2 sec stun. ppl bought boots of mobility and roamed with him. Thats how it should be if riot truly want interaction. by default everything is dodgeable and or takes some sort of aiming to land. Skills that are reliable and still have great dmg/cc should be considered overpowered, and must result in the champ having other weaknesses. TYPICALLY a champ that has shields, windwall and aoe cc is a support, like braum. if yougive braum great dmg and dashes and scaling then youre blurring out the lines between the roles and youre definately not getting more interaction.
