How to read coverage in the builder
What coverage analysis is for
Coverage analysis on this site is a fixed rule set over your current lineup. It is not AI guesswork. It reads vehicle stats and roles from community data and compares your chain to patterns that usually survive Ground RB.
Use it after you drop vehicles into slots. Strengths tell you what is solid. Gaps warn about missing roles. Weaknesses flag spread or backup problems that get worse in uptiers.
BR balance and spread
The tool looks at top battle rating and how far your other spawns sit below it. Wide spread means your backups fight in lobbies tuned to your tip vehicle.
Fix spread before you add another high-tier premium. A tighter band with three honest spawns usually performs better than one star vehicle.
Roles, backups, and anti-air
Role coverage asks whether you have a front-line tank, something that can flex or scout, and anti-air. Missing anti-air is one of the most frequent gaps.
Backup depth checks whether you still have meaningful lives after the first death. One tip tank with no same-tier partner shows up here as a weakness.
Uptier resilience
This section summarizes how painful an uptier will feel with your current shells, stabilizers, and mobility. It is a hint to adjust spawns, not a promise about matchmaking.
When weaknesses pile up, open a nation/BR guide for your bracket and compare your chain to the recommended spawn order on that page.
Check fit and Suggested next
Check fit asks whether a premium or new vehicle belongs in the lineup you already built. It looks at BR band, roles you still miss, and whether the new card duplicates something you already spawn.
Suggested next points at a useful add when coverage still shows a gap: often SPAA, a same-tier backup, or a flex spawn. Treat both as hangar advice for this set, not a shopping list for every tree.
Open the builder, drop in what you own, then use Check fit or Suggested next before you research or buy.
After you fix gaps
Re-run analysis after every swap. Share or publish when the lineup matches what you actually queue. Guides and Discover stay separate: guides teach spawn order, Discover shows community lineups.
