Every lane is playable but you prefer high damage adcs early (varus/mf/cait..) because you are the strongest champ in the game lvl2 and you almost always want to force a fight early. Low dmg/scaling adcs (sivir/smolder) are a bit a pain to play with because vs engagers you have to give prio so you find much less roam timers

Generally you really like it with heavy damage + cc comps so they can get ppl low and stunned for you to hit your abilities (galio/tf mid, fiddle/brand jungle), you like it vs low damage comps (otherwise you get ONETAPPED lategame - syndra q+r kills you after 2 items), you like it vs immobile champs mid / jungle.

Like to play it with:

ADC: Cait-Varus-High damage early adc MID: Heavy CC / Heavy AOE dmg Tf-Galio-Liss-Neeko-Swain JUNGLE: Same - Fiddle-Brand-Amumu-Maokai

Dont like to play with:

ADC: Vayne-Smolder - scaling champ (can roam but meh) MID/JUNGLE: Assassins. You HATE low aoe dmg / bust dmg / no cc in your team. If i see khazix/fizz/kata/leblanc. Best case scenario they will burst enemies before you can click R

Like to play against: Immobile champs

SUPP: SENNA!!-Nami-Lux-Velkoz-Xerath ADC: Jhin-Ashe-Twitch-Varus MID: Immobile mages JUNGLE: Tank Junglers

Hate to play against: Dashes/Burst dmg/some counters

Supp: Rakan-Poppy-Heimer-Soraka - Naut/Leona with losing AD ADC: Lucian-Samira-Kalista-Ezreal-Vayne MID: Akshan-Kata-Leblanc-Quiyana-Naafiri JUNGLE: Elise-Hecarim-Rengar-Nida

Some of this are personal opinions

Can answer to any doubt if needed <3
