I’ve actually seen it (though in more recent times just 20 or so ppl and keep in mind people already have characters on certain servers or get them leveled quick) and it can be much easier to coordinate with server transfers since people can just transfer in with max characters /all engrams/mats.
Mega clans ( by clan I mean multiple clans working together to fight another big group or just wipe a server b/c somebody cried for help trying to get a mob to do the work for them) try to bring as many numbers as possible. Usually no one can get their full crew on once the servers hits max players, so people have to cycle clan mates in/out of sub clans to make room for players who manage to get through the queue. Each side can have upwards of 50 players but not everyone obviously can be on the same server at the same time so they go raid other servers enemies play on while they’re busy fighting on the main target server.
Its a big long confusing mess of people who only want constant fights, mayhem or destruction, and yes I see the cat herding first hand. It’s ridiculous tbh but people get bored without it

I’ve seen this happen with 20 or so people not too long ago at a time and they usually don’t stay low lvl for long b/c they’re organized with someone already setup helping them. Of course there’s already another 10 15 players on the server they’re there for

The only counter is numbers. There’s really no such thing as alpha tribes either, just who has the most numbers at the time to force others to body vault/ice vault/mesh. Even then you can literally pack up your base and hide in unintended places so no one who’s one step ahead is ever really wiped. I will say though its too easy to raid. Raiding a well built base should take a bit of time and effort not 10 min or less with numbers. Whole other balancing topic though

Correct, and I’m saying maybe it should be that way through a daily XP cap. The whole problem with pvp servers is that its too easy to level up, farm up and raid t3 end game bases. If large groups were slowed down while base defenses were buffed etc maybe there would probably be less server hopping and more incentive for people to stay on servers and fight it out. then again its kinda too late for changing the leveling meta unless servers are wiped too (likely wouldn’t happen) Which brings me back to one of the points of a temp player copy. A limited way for people to go pvp on other servers (with some restrictions) casually while staying on their home server. The other point was that its probably easier to implement this since the code should be there at least in part.
