Read the title. It's literally as simple as looking for up a video or just listening to the damn game when it tells you to bank. Don't hold onto 15 motes in the middle of a pack of enemies alone cause you got greedy, don't try to kill a group of enemies alone in the first place. Edit: I was mad before and didn't think to include tips, so here they are. 1. Grab motes, check and see if your teamates are one or two off a blocker and let them pick them up if you don't need them. Banking 15 motes doesn't help as much as you may think so try to bank small and often. 2. Keep track of the enemy invasion portal. Every 25 motes a team deposits, they can invade you. There will be a small symbol above their mote bar if they can invade. If you have motes for a blocker of any sort, bank them ASAP to prevent them from blocking, then invading as a combo. 3. Don't invade if the enemy team have no motes. It will be more of a waste to your team than the enemy team. 4. Don't invade the second the enemy primevil is up, wait a little bit or until they begin their damage and then invade. 5. Try to use meta weapons, self explanatory really. 6. Don't push an enemy wave alone unless you have a super but even then be cautious. If you have something like insurmountable skullfort however, you can chance it if you're confident and know when to back off if necessary. 7. Finally, please for the love of God don't invade with motes. Also if the drifter tells you to bank for a primevil you should do so immediately, do not try for a large blocker, if the enemy invades or you die, you will hold your team back and even if you get the blocker, you've sacrificed precious time. I seem to have missed the most important rule of gambit, it's ok cause it's quite simple you see. 8. When in doubt, lose the round. It's ok, Bungie want to throw away skill for no reason and will actively help you win the next round for free and with little effort required!
