"Unconventional" Picks
Just thought I would make a discussion about unconventional champs in their not-intended lanes.
TOP
Has armor penetration, two gap closers, poke (in the form of her e). Problems with early mana costs and lack of sustain.
Has an AA empower, sustain, burst, slow/snare, invis engage/escape. Lack of tankiness and lack of a gap-closer without ult.
Has a gap closer/slow, poke, burst, generally safe in lane with amazing kill potential. Lack of tankiness and easy to focus/shutdown in teamfights.
Has poke, sustain, stun, slows, AA empower, ms boosts. Problems with early mana costs and lack of tankiness.
JUNGLE
Has a stun, easy way to gank, amazing shred w/ devourer. Problems with early clearing, no sustain or tankiness.
Has decent clear, easy ganks, can choose devourer or runeglaive. Has no sustain or tankiness.
Has decent ganks, decent clear, can choose runeglaive or cinderhulk. Has no sustain, and an awkward pre-3 clear.
Has easy ganks, slow/stun, cinderhulk is super useful. Has a slow clear, and cant eat Red or Blue.
MID
Has pretty surprising damage, burst, slow, and a major-impact ultimate. Has problems going in if full ad, so tankiness is required.
Has ridiculous damage/poke, polymorph is extremely impactful, ultimate is really useful. Ends up being a second support lategame.
All of his abilities do massive damage even if you only have a little bit of AP. Ends up getting focused easily if not tanky.
Has pretty good damage, free armor pen, and an impactful ultimate. Gets picked off pretty easily, needs to wait for the right oppurtunity.
SUPPORT
If the enemy botlane has no real escapes or peel, he's amazing. Otherwise, sub-par. Has armor pen, slow/knockup, good cc chain.
Good bait w/ passive, two knockups, slow. Has no heal, shield, ms boost, nothing supporting.
Has a small knockup, armor boost + return damage, taunt, and a massively damaging ultimate. Has problems with cooldowns.
Has a slow, a snare, a gap closer, and a stun. Has mana problems, and has no supporting abilities.
ADC
Has a slow/stun, movespeed boost, impactful gap-closer, massively impactful ultimate. Has no AD scaling.
Has charm, movespeed boost, ridiculous gap-closer. Has no AD scaling and mana problems.
Has slow/snare, gap closers, and juking ability. Has no AD scaling and mana problems.
Has movespeed boost, poke, knockback, AD scaling, and 6 abilities. Has mana problems and no ultimate, hard to master.
These are just my OPINIONS, disagree as you may, add some unconventional people in the comments below.
Can be tanky, has a targetable slow, suppressing ultimate, ranged, scaling of both kinds, has a shield for engages/escapes.
