The tier criticism is valid and one I take seriously, although I think you missed the mark a bit on what comp you left it on lol. This is the most played comp in every elo and most played comp in every competition. I guess it’s “bad” if you are judging it by how often it wins the game. But no one expected this comp to win outside of Bronze for Life (which got nerfed this patch) and other broken setups.

But moving back to the heart of your complaint about tiers: Yes, tiers on this site have some issues. Let me break down my general framework for tiers:

OP = 3.3 average or better USUALLY, or worse average with high play rate and extremely high community sentiment on how broken the condition is.

S+ = 3.6 average or better USUALLY, or worse average with high play rate. Usually the things that people are excited to get, but not snap picking like OP conditions.

S = I don’t look at averages for this tier. Sentiment is generally that no one wants to play a line below this point. If you are a high level player, you aim to always have a line that is at least S tier or better. You will not see a comp baseline be in S-tier or higher unless the meta is very poorly balanced by Riot.

A = Averages are only a small factor for this tier. Generally what’s important here is how popular the comp is (pick rate), how consistent the comp is, and how good the comp feels in the meta. For example, this comp is A-tier because it is the most consistent comp in the meta. Can play it from any spot and go for top 4 usually. Kha’Zix is A-tier because even though it’s a better performing comp, it’s more conditional than this comp. Note that ANY good condition with an A-tier line brings it up to S-tier, which again is the minimum baseline any “good” player is aiming for.

B = Averages are only a small factor for this tier. B-tier covers the widest range of comps on the website. B-tier covers the widest range because it accepts a wider range for comp consistency and comp strength. Sometimes a B-tier comp is really strong with the right conditions, but can’t be played reliably without those conditions. Sometimes a B-tier comp is highly consistent, but weaker than most A-tier comps. The general feeling of B-tier comps is “I will play it instead of A-tier comps only if I can’t play an A-tier comp OR if I have a good spot for it”. Because A-tier comps are usually contested more, sometimes you really can’t play them and have to settle for B-tier.

C = Averages are a bigger factor for this tier. Most comps in C-tier are not playable without conditions. Remember the goal is to play a line that is S-tier or better usually. It’s hard to get a C-tier line to that baseline. So C-tier comps are already getting dangerously close to unplayable. Usually 4.7 to 4.9 range, sometimes even worse.

D = Comps that are unplayable without broken conditions. Usually 5.0+ average without conditions. Usually comps that were viable earlier in the set, but faded out of the meta due to new discoveries or balance changes. Sometimes meme comps that people like playing even though they know it sucks.

It’s rare I put the base tier of any comp outside of “A”, “B”, or “C”. S or higher is almost never because it’s very rare for a comp to reach S-tier strength without any good conditions (which is what baseline S-tier ranking is saying). It requires really bad balance from Riot. D-tier is used sparingly when I think a comp should just not be played, even with conditions most of the time.

EDIT: Also, the issues with “tiers” is why I introduced the second ranking system for comps “Default”, “Meta”, and “Other”. Default comps are consistent and most popular comps. Meta comps are ones you should know about, but more situational. Other are comps that are usually highly situational, but can still be playable. I still do not display those labels on this page, but I need to at some point.
