I like that you have made some changes already, but really you need to do a few more things to make it better. For example: The fallen Vandals that can crawl sprint while invisible, from where they spawn. Right into the seraph tower box. Not to mention cabal Minor/Major/Bosses, can use their jet packs to cover large distances.... To the point where it only takes them a few seconds to reach, or for the fallen sake 'sneak' into the box to cause the 'enemy interference has overwhelmed the support tower' It makes it so difficult to kill them all quickly, especially when multiple towers can pop up at the same time! And also, Champions is the enemy units that require seasonal mods to kill right? Overload, Anti-barrier, Unstoppable. That particular part of the event is easy! It's getting to that final part of the event that's too difficult. And again also, you have made it so that being over-leveled on a enemy will not give any useful benefits when Shadowkeep launched, so reducing the power level on these 'champions' will have done nothing! And add in the fact that there's no matchmaking with other guardians for this event!
