How the ROV Tier List Works: What S+, S, A, B, and C Actually Mean

Most tier lists hand you a grid of letters and expect you to nod along. That is useless if you do not know what the letters mean or what went into them. So before you trust any placement on this site, here is exactly how we build the ROV tier list and how to read it without fooling yourself.

What each tier actually means

A tier is a shorthand for "how much does this hero overperform in the current patch, in the right hands." It is not a measure of raw power in a vacuum, and it is not a popularity contest.

S+: Pick-or-ban. These heroes warp draft. If you do not pick them, you should think hard about banning them. They win games they statistically should not.
S: Top of the meta. Consistently strong, low-risk, high-reward. Pick these into most drafts and you are rarely punished for it.
A: Genuinely good and reliable. Often more dependent on draft fit or player skill than S-tier picks, but a strong A hero in a comfortable matchup beats an S hero you cannot play.
B: Situational. Works in the right comp or the right hands, but asks more of you than the tiers above. Plenty of B heroes are secretly great if you main them.
C: Below the curve this patch. Not unplayable, and a few have win rates that quietly embarrass their tier, but you are fighting the meta rather than riding it.

The single most important thing to understand: a C-tier hero you have 200 games on will beat an S-tier hero you picked for the first time. Tiers describe the meta. They do not describe you.

What goes into a placement

We do not pull these out of thin air, and we do not just copy a global list. A placement comes from three things, weighted in roughly this order.

First, current Thai-server ranked performance. Win rate, pick rate, and ban rate at Diamond and above. Win rate alone lies, a 70% win rate on a 0.7% pick rate is usually a handful of one-tricks, not a strong hero. We read those numbers together.

Second, the meta context. A hero is only as good as what they are played into. When the meta is full of immobile carries, dive assassins rise. When it is full of dive, zone-control and peel rise. A placement is always "good against what is currently being played," not "good forever."

Third, the sources that the English-speaking world cannot read. The serious ROV meta discussion lives in Thai, on channels like kritngi and Doyser, and in Thai ranked itself. We watch it, read it, and translate it so you do not have to sit through a 25-minute Thai video to find out a hero got quietly buffed.

Why our list can lead the global one

Here is the part most English players miss. The Thai ROV server receives patches one to two weeks after the global Arena of Valor servers. That lag is an advantage if you use it. Global English tier data gives us a preview of where the Thai meta is about to move, so we can flag rising heroes before they spike on your server. If you read both, you get to pre-build your ranked pool around heroes that are about to get strong.

How to actually use the list

Do not draft straight off the grid. Use it like this:

Filter by your role first. A great mid pick does nothing for you if you play roam.
Check the matchup, not just the tier. Every hero page lists who counters them and who they counter. A B-tier hero into a favorable lane beats an S-tier hero into a bad one.
Weight your own comfort. If you have a 60% win rate on an A-tier hero and a coin-flip on the S-tier flavor of the month, play the A-tier hero.
Re-check every patch. Placements move when the patch moves. A hero that was S last cycle can drop hard on a single nerf.

The honest version

A tier list is a starting point, not an answer. It tells you where the meta is leaning so you can make informed picks. It cannot tell you whether you can land the combo, read the fight, or hold your nerve at 30% HP. That part is on you. Use the list to stop griefing your draft, then go put in the games.
