Did shelters event get changed?
From what I have seen, they are also 3-4 levels higher than they were as well. Which means they obliterate the bots in low level gear, and then obliterate the 2 real players left to face the horde of mini-veterans alone.
Not only do they attack as soon as they spawn, they spawn “invulnerable”, so classes that usually can not tag unless they are pre-spamming the spawn locations are effectively shut out because as soon as they exit their invulnerable state, they pretty much get obliterated before lower DPS classes can tag them.
