Why does it feel like the vibe just collapsed overnight?

The first couple of weeks felt completely different. People talked, teamed up and showed intent, good or bad. Now it's like something flipped. Almost everyone goes straight KoS, no comms, cheap tactics everywhere. Try do quests or fight ARCs and someone just appears and deletes you...not a word.

I know it's an extraction game and that PvP comes with it and I get that the novelty wears off once people learn the maps, level up and start falling back to PvP. I want that tension but ARC at least feels like it leans a bit more toward cooperation and shared moments than some of its competitors. The shift was just so sudden and I hope it balances out, because right now it kind of takes away from what made ARC feel awesome. To counter this you pretty much have to do the same, then everyone follows. Anyone else feeling this?
