Top 20 tier 1, top 30 tier 2 (in my opinion)
T1 players might also make a team T1 despite their performance???
at this point i think every team in the top 25 is tier 1, they can compete and can be a threat to anyone.
Tier 1 means constantly being in the play offs of the big tournaments
Tier 1 are the team who've been in the top20 for several months and have participated in a lot of tier 1 events, and have consistent tier1 results
TIER 1: GAMBIT, NIP, VITALITY, G2, FAZE, HEROIC, VIRTUS PRO, OG, BIG, LIQUID,MOUSESPORTS, SPIRIT
TIER 1.5 : ENCE, FORZE, ENTROPIQ, FIEND, GODSENT
TIER 2: FNATIC, SKADE, GODSENT, SINNERS, COL, DBL
TIER 2.5 : DIG, LDLC, EG, LYNGBY ....
EDIT : DBL NOW T2
I don't think it's something that's set in stone. The scene will go through phases where there are more elite teams and less elite teams but more "good" teams as a result.
I think a team who is regularly making playoffs of large events is a tier 1 team. There are often "gatekeeper" teams who will normally lose to Tier 1 but will normally beat the teams below them; you can call that tier 1.5 if you want.
Tier 2 will be teams who perform well at smaller events and often qualify for big events (although qualification is easier outside of Europe so bear that in mind).
Copenhagen flames, sinners and movistar are becoming tier 1
It depends, you can't just say that for example top 10 teams are tier 1. In 2018 for example Astralis was the only tier 1 team and the rest were tier 2+. At some points there might not be any teams dominating and then maybe the top 15 teams are tier 1. And some teams are very inconsistant and play like a tier 1 team some days and like a tier 2 team other days, but are still in the top 10. I never really liked ranking teams in tiers.
Tier 1 are teams that constantly play in tier 1 tournaments and also occasionally make the playoffs, so I'd draw the line at ENCE and exclude Spirit, EG, Fnatic.
Tier 1.5 are teams that constantly play in tier 1 but most of the time aren't good enough to make the playoffs (so the teams I just mentioned)
Tier 2 are teams around top 20-40 who frequently make the playoffs of t2 events such as pinnacle cup, elisa, etc. So it's Copenhagen Flames, Entropiq, DBL Poney, AGO, Lyngby Vikings, Fiend, SKADE etc
Tier 3 are teams that play in t2 tournaments but most of the time don't make the playoffs. (SaW, Eternal Fire, etc)
Tier 4 is anything below.
tier 1 = teams that constantly makes it to playoffs
tier 2 = teams that play in tier 1 events, and maybe makes it to playoffs once in a while, but they are not contendors for winning the event
tier 3 = teams that nevee qualify to big events
tier 1 teams are the most consistent at winning the big events matches.
tier 2 teams are half consistent than tier 1
tier 3 teams are inconsistent
Top 1-15/20 but not a weekly ranking but for example 3 months. In order to be a T1 team, it would be appropriate to have some decent results on T1 events consistently.
if you are regularly playing tier 1 events then i think its a tier 1 team
If there are boundaries, it's not Top 10/Top 20/Top whatever. It has to be rating. Because, for example, if the team ranked 9th has zero chance to win against the top opponents, then clearly they're not tier 1 even though they're top 10. Or could be that tier 1 contains more than 10 teams. In a highly competetive era there are more top tier teams than in a less competetive era. The tier boundaries depend on how good the teams are, and rating is a better way to account for that than rank.
Ofc rating isn't optimal, and there are many ways to draw the boundary, but all of them are more or less arbitrary.
Its about what tier events you attend
Tier 1 attends tier 1 events like ESL cologne or Blast finals consistently, teams ranging from Navi to OG or Faze
Tier 2 attends tier 2 events consistently, sometimes making it into tier 1 events, rarely performing too highly at them tho. Tier 2 Ranges from teams like Ence to teams like lyngby vikings
Tier 3 are the teams that dont even make tier 2 events every time and are never in tier 1 events, tier 3 teams also never win any events
Nip faze vitality astralis tier 1 lan gods
Gambit navi g2 heroic tier 2 onliners
