War Thunder
Lineups
War Thunder lineups should share a battle rating neighborhood. A single premium that uptiers everything is how you play 6.7 with 5.3 backups.
Fill the BR, do not spike it
If your best tank is a full step above the rest, you will see stronger enemies while your backups are made of paper.
Bring a plane or SPAAG if the BR has CAS. Ignoring the sky is a choice to eat bombs.
Spawn points are a budget
A heavy first spawn can leave you with nothing if you die. Know the cost of your second vehicle before you yolo the first.
Crew skills are quieter than new tanks
A trained crew on a tank you know beats a stock vehicle you just clicked in the tree. Finish modifications.
