That’s dependent on software architecture and honestly the more in a common group the better for this game.
I’ve heard people complaining about not enough active players, or in your shoes viv not enough people to hit. Segregating the user population is just going to make things worse for the community and for the game in general in my estimation.
If SG has a scalability issue on their infrastructure, well they can always find someone like me on the infrastructure side as I’m not exactly unique in the industry… my guess is they’re just load balancing in a cloud somewhere but I’ve never taken a sniffer to really see where all the connections go.
There are other games where it does make sense, but typically that’s in more of a P2W model than what this is where there’s massively diminishing returns to spending money.
It may be worth further discussion but personally I’d rather SG just solve the capacity issues and keep everyone in one big group… I’m thinking they should’ve anticipated though a large spike in players for this, but overall the rollout wasn’t anywhere close to the worse I’ve seen: WoW was down hours at a time in it’s early life for example.
