Hello,
Good introductory video guide on the Rikti mothership raid! I just want to point out a couple of things.
1. You mentioned, "[...] You want to get all six done (bombs planted), because that increases the amount of time that you'll have in the bowl." That's not entirely accurate. If you are in a league of 24 or fewer people, you only need to plant two bombs. If you are in a league of 25 or more people, you need to plant three bombs. In regards to the timer, any additional bombs planted does exactly nothing.
Dropping the Rikti mothership's shield nets you ten minutes. Planting one bomb nets you three minutes. If you're in a league of 25 or more people, planting a second bomb nets you three more minutes. Spawning U'Kon Gr'ai (the second or third bomb, depending on league size), nets you ten minutes. Defeating U'Kon Gr'ai nets you five additional minutes. So, if you're in a league of 24 or less, that's 28 minutes in the bowl. If you're in a league of 25 or more, that's 31 minutes in the bowl.
Planting a fourth, fifth, or sixth bomb is only good for badge credit.
2. The ejection of the league from the mothership back to the Point du Hoc Vanguard compound only occurs in the zone Rikti mothership raids. In the Rikti mothership raid trials, the Rikti just stop spawning and eventually retreat back inside the mothership when the raid ends, leaving your league all alone in the bowl.
All in all, good video guide!
