How do the counter and synergy tier lists work?

When you click on a hero in the Heroes page, you'll see Counter and Synergy tier lists. These show how well other heroes perform against or alongside the selected hero, based on community win rate data at your rank division.

Tier Breakdown

Tier	Win Rate	Meaning
S	53%+	Dominant
A	51.5-53%	Strong
B	50-51.5%	Slightly favorable
C	48.5-50%	Slightly unfavorable
D	47-48.5%	Weak
F	Below 47%	Very weak

Win rates shown in tier lists are adjusted for sample size. Matchups with few matches shrink toward a neutral 50% so a 60% win rate in 20 matches doesn't outrank a 54% win rate in 5000 matches. The tier bucket and color use the adjusted value; the raw observed win rate is shown beside it for reference.

Heroes are sorted by adjusted win rate within each tier (best first) and grouped by role.

Counter vs. Synergy

• Counters show which heroes have the best win rate against the selected hero, useful for knowing who to pick into an enemy hero
• Synergies show which heroes win the most alongside the selected hero, useful for coordinating with your team

If you have personal matchup data, hovering over a hero portrait will also show your own win rate against or with that hero.

Data Quality Indicators

Not all matchup data is equally reliable. At very high or very low ranks, some hero matchups may have very few matches played, making the win rates less trustworthy.

Counterwatch shows you how confident the data is for each hero:

• Full opacity. High or moderate confidence (200+ matches). The win rate is reliable.
• Dimmed (faded). Low confidence (50-200 matches). Take the win rate with a grain of salt.
• Dimmed with dashed border. Very low confidence (fewer than 50 matches). The win rate may be misleading.

Hover over any hero portrait to see the exact match count and a colored confidence indicator in the tooltip.
