The marquee change in the latest This Week at Bungie is likely the changes the Gambit team is making to the PvPvE mode that was introduced with Forsaken last year. When Season of the Drifter starts, the blockers you’ll spawn by banking motes of light are going to be different, giving players more incentive to save up for the big ones.
The small blocker you’ll spawn in the enemy area for banking five motes of light is changing from a Phalanx to a Taken Goblin with less health. The medium blocker will henceforth be a Taken Captain, replacing the Knight, and the large blocker will be a Taken Knight, replacing the Ogre. Both the Captain and the Knight will have more health than the original blockers, making it worthwhile to save up motes – Goblins don’t tend to slow most players down much.
