I managed 600k with BAM (L) Boba and Cad. Mostly focus on bombs. It’s about tracking Bobas cooldowns. When his AOE is up, use Cad to reduce TM and BAM basic for debuff setup for boba to executor after his AOE. Almost never basic on Kyrat with Cad or Boba hit bombs instead bam sets bombs. Took me some practice but hit 600k with a 3 man tema. Boba R8 Cad r6 Bam r5.
