Does exiting the battle after getting killed affect the scoring

Lower tier tanks will only play on a limited subset of maps, to give players the chance to familiarize themselves with them quickly.

Battle Tiers 1 and 2 fight on these maps:

• Malinovka
• Himmelsdorf
• Mines
• Province

Battle Tier 3 additionally fights on these maps:

• Karelia
• Prokhorovka
• Ensk

The province map is not available for Tier 4 and above. For Tier 4 and above the map picked should be random, but in practice this is not the case. The reasons behind this are not completely clear, although wargaming does seem to give new maps a higher chance of appearing.

See this forum thread on map distribution stats for more information on the actual frequency of appearance of some maps.

Most SPGs have rather small gun arc so you need to plan what you do beforehand. Most SPGs with big gun arcs are the ones which were added in 8.6 patch (the patch that nerfed SPGs to the ground). That means you need to know the maps well, know where you can shoot to which positions and where the enemy is going to be usually. Plan ahead and preaim, dont be hasty in swapping targets around the map and focus on one area at the time. Patience is needed and its quite dull at some points too, unfortunately.

Buying gold ammo for SPGs is not really needed. I have 2 T10 artys (US and French) and I havent really used any premium ammo along the way.
