Free Agent - NA
This tierlist is my opinion. I do not claim supreme knowledge of the game nor claim these placements are indisputable. Champions within a rank are not ordered, champions within a class are not ordered. Think of the ranks with the titles I gave them, not by the SS, S+, S, and S-.
ss
All the Champions are Bannable: Also consistent first picks
Zhin: Survivability, tank killing or great poke w/ guillotine and yomi respectively
Andro: Probably the most consistent flank in the game, verticality, weak to zhin duel but more consistent poke
Atlas: incredible abilities, can be run with big shield and dejavu depending on your teams comp, dmg buff really helped him be competitive
Inara: most consistent point tank in the game, high dr and increased healing w/ 675 per shot makes her a monster on the point
Ash: best brawler, can fight w/ any champion in the game, self-sustain
Raum: high self-sustain, 3 sources of DR, weak to CC, great at holding lanes and making openings for flanks
Terminus: better than inara on ice mines, maybe jag falls, ability to pocket allies w/ siphon, bursty point tank with calamity blasts
Io: luna can cap, enables 5v5 zoning, dr on heal can save in late game
Jenos: luminary buff enables dps carries to carry harder, if you dont believe in your dps, pick corvus, does not need LOS, lift CC
Corvus: heals more than jenos, provides life steal, does not need LOS
Strix: strix is a problem for this scenario; strix is invisible, he hits someone for 1200, 1 second between shots, fires again for 1200. This is 2400 in 1 second because people can not react to the first shot. This is the problem, his fire rate should be reduced to 1.2 sec is my recommendation.
Viktor: Most consistent dmg, burst mode can enable dueling w/ flanks
Vivian: Consistent dmg, burst from mines, shield and movement speed make hard to kill
Sha Lin: cripple arrow w/ explosive talent makes him a chore to dive as a flank, great poke and mid range pressure
s+
Filler Champions: serviceable replacements to fill in for banned champions above or for specific maps
Maeve: great all a rounder, dr, cat burglar burst
Evie: Great poke, weak to intelligent hitscan players who know your blink spots
Buck: pseudo offtank, provides pressure and survivability to steal attention from opposition
Khan: great against Fernando, ash, raum; can brawl but not as effective, ledge maps are strongest for him
Fernando: Aegis can allow backliners to push up, provide pressure by enabling dps, best on level maps
Ruckus: a larger buck, provides great dmg from side lanes, weak to being counter dove
Mal'Damba: the all-around healer, does not do anything broken but heals very well and provides utility with stun
Furia: provides dmg in addition to bursty heals, great ult, weakest against blaster comps who injury multiple allies
Grover: best champ for dual support, provides cripple, dr on heal and self sustain
Kinessa: More dmg per shot than strix, weaker to flanks
Bomb King: most consistent blaster in the game, grumpy bomb stun, can lock down tunnels and narrow lanes
Cassie: still consistent dmg, burst potential with blast shot talent and big game, can be pressured more easily than higher dps
Willo: if the enemy team has no/weak hitscan, picking willo with MB (on a high ground map) can ruin their composition
Tiberius: second to ash in 1v1s, provides great tank pressure and not as susceptible to flanks when he has CT
s
Niche Picks: Pick-able for certain compositions or punishing enemy drafts
Koga: enabled by torv + jenos/corv, provides great consistent smg poke and agility spam; otherwise, not worth it
Lex: discovery enables great 1v1 potential against many champions and sustain, no verticality
Talus: no verticality, can be in multiple places with teleport, weak to grouped up comps
Makoa: shell shield provides for small zone control, if not broken, koa can be counter rushed, can not push lanes as effectively as other off tanks
Torvald: can provide benefits similar to jenos/corvus in enabling carry dps, dont pick if dps sucks
Barik: weakest of the point tanks, shield nerf and lower hp pool with nerf to his healing cards has weakened him
Ying: similar to damba regarding healing, great ult, no utility
Pip: weaker version of buck, better ult
Grohk: closed maps and enemy with multiple bounce targets allows grohk to bring consistent dmg
Seris: soul collector enables an aggressive, 3000 hp, self-sustatining dmg with mobility, ruined by caut and flanks who can follow her
Lian: can bring dmg comparable to other dps, weaker to flanks even with auto aim and snipers
Drogoz: punish pick for no hitscan, similar to willo but less imposing without deadzone
Tyra: similar to lian, better vs flanks, less mobility, mark utility
Imani: fire stance, can surprise flanks with 2000k burst, otherwise weak to dives
Dredge: countered by term, then weak to flyers despite harpoon spam
s-
Don't Pick For any Reason: none of these champs do anything worth picking them for
Moji: can burst people, weak to counter pushing, loses most 1v1s, no verticality
Skye: weak to counter pushing, loses most 1v1s, can poke with poison bolts, no verticality
