Pick your Tank Wisely
Grand Battles is a very different game mode, meaning certain Tanks that work in a standard Random Battle might not work here. It’ll take time to find out which Tanks are great for the game mode and which ones are… less great, but when we do it might be a good idea to acknowledge that.
Grand Battles – being part of Random Battles – can be disabled like the other game types (such as Encounter, or Assault). If you’re playing a totally out-of-meta Tank for Grand Battles, I’d recommend unchecking that box in advance to avoid the disadvantage and ensure you only get what you’re used to, before checking it again when you’re ready to play a vehicle that fits the meta.
