A little summary on the new Guardian’s gala from someone who likes to do these seasonal events:
Drops can be overseer personal effects, various skins eg Glacial augment, and various boosters (even Agency lvl IV). Very happy with this since you can earn very good isk if you are able to farm these.
Thing that’s kinda cool is there are sometimes two levels of bosses. First a machariel then a bigger boss afterwards - the vindicator. The second boss has a fatter bounty and drops better rewards.
Incoming DPS doesn’t seem to be too high, especially if you got a lot of people. I demonstrate the site here in a Rattlesnake: https://youtu.be/RKAHUMApnKE
