Keep all vehicles within 0.3 BR
Acceptable Gap
0.7 BR for SPAA is okay
Avoid
1.0+ BR gaps waste spawn points

⚠️ BR Black Holes - Avoid These!

6.7 BR Extreme
The 6.7 Black Hole
Constantly uptiered to 7.7 facing HEAT-FS and stabilizers
Affected: Tiger II, T34, IS-2 1944
Solution: Move to 6.3 or jump to 7.3+
5.7 BR High
The 5.7 Uptier Zone
Frequently faces 6.7 heavies with superior armor
Affected: Panthers, T-34-85, Centurion Mk I
Solution: Drop to 5.3 or push to 6.0
4 BR Moderate
The 4.0 Compression
Mixed with both 3.0 and 5.0 vehicles regularly
Affected: M4 Sherman, Panzer IV F2, T-34 1942
Solution: Push to 4.3 or drop to 3.7
8.7 BR High
The 8.7 ATGM Zone
Uptiers face thermals and modern APFSDS
Affected: Early MBTs without thermals
Solution: Move to 8.3 or 9.0+
11 BR Moderate
The 11.0 Compression
Narrow BR range makes every match similar
Affected: Most top-tier vehicles
Solution: Accept or play lower tiers

🔬 Matchmaking Mechanics Explained

📊 BR Spread Rules

  • • Your highest BR vehicle determines matchmaking bracket
  • • You can face enemies +/- 1.0 BR from your highest
  • • If top BR is 5.3, you face 4.3-6.3 enemies
  • • Lower BR vehicles in your lineup don't affect matchmaking
  • • All players in a squad use the highest BR in the squad

🎖️ Spawn Point System

  • • Start with 0 SP - first spawn is "free" (still costs SP but you have enough)
  • • Earn SP by scouting, damaging, killing, capturing, and assists
  • • Each vehicle has a base SP cost (tank: 150, SPAA: 100, CAS: 450+)
  • • BR gap increases spawn cost: 0.3 gap = +30 SP, 1.0 gap = +100 SP
  • • After death, respawn costs increase cumulatively

⬆️ Uptier Mechanics

  • • Uptier probability varies by BR bracket (45-70%)
  • • Popular BRs (5.3, 6.7, 7.7) face more uptiers
  • • Off-peak hours = more uptiers due to smaller player pool
  • • New vehicles/updates temporarily shift uptier patterns
  • • Being in a squad doesn't affect uptier chance

🔍 Hidden Factors

  • • Queue times under 30s = likely uptier (filling matches)
  • • Queue times over 2 min = likely downtier (creating new match)
  • • Region affects matchmaking pool size (EU > NA > Others)
  • • Time of day impacts available players and BR distribution
  • • Event vehicles temporarily increase certain BR populations

✨ Optimal Lineup Examples

Perfect Lineup 95% Efficiency
• 5.3 BR Tank (Main)
• 5.3 BR Tank (Backup)
• 5.3 BR Light Tank
• 5.0 BR SPAA (-0.3 gap)
• 5.3 BR CAS Aircraft
All vehicles within 0.3 BR = minimal spawn costs, maximum efficiency
Acceptable Lineup 70% Efficiency
• 6.7 BR Heavy Tank
• 6.3 BR Medium Tank (-0.4 gap)
• 6.0 BR Tank Destroyer (-0.7 gap)
• 5.7 BR SPAA (-1.0 gap)
• 6.7 BR Fighter
Larger gaps increase spawn costs but lineup is still functional
Poor Lineup 45% Efficiency
• 7.7 BR MBT
• 6.7 BR Medium Tank (-1.0 gap)
• 5.7 BR Light Tank (-2.0 gap)
• 4.7 BR SPAA (-3.0 gap)
• 6.0 BR Attacker (-1.7 gap)
Large BR gaps make spawning expensive and lower BR vehicles ineffective
Terrible Lineup 20% Efficiency
• 10.3 BR Modern MBT
• 8.0 BR MBT (-2.3 gap)
• 6.7 BR Heavy Tank (-3.6 gap)
• 5.3 BR SPAA (-5.0 gap)
• 7.3 BR Jet (-3.0 gap)
Massive BR gaps make lineup unusable - most vehicles can't be spawned

💡 Key Takeaways

1️⃣

Minimize BR Gaps

Keep all vehicles within 0.3 BR of your highest. This minimizes spawn costs and ensures all vehicles remain competitive.

2️⃣

Avoid Black Holes

6.7, 5.7, and 8.7 get constantly uptiered. Drop to 6.3/5.3/8.3 or push higher to escape the uptier trap.

3️⃣

Balance Your Lineup

3-4 main tanks, 1 SPAA, 1-2 CAS aircraft. Don't bring 7 tanks - you need variety for different situations.

4️⃣

Plan for Uptiers

Expect 50-70% uptier rate at popular BRs. Build lineups that work when uptiered, not just at same-tier.
