I want to play a game where I can put together a team or items so that they work together really well and it's satisfying.

I'm not talking about nitty gritty things like oh this gives 50% more damage when paired with this. I mean more like oh this character freezes the enemy then this character deals extra damage to frozen enemies and then this character stuns unfrozen enemies long enough to re freeze them

I'm new to this but I don't understand how you're meant to find the correct biggest community if it's on a different server than the one you're on.

If I search for it I only see communities on the same server as me. How do I know if a community just doesn't exist or if it's just on a different server?

Is there a way to search for the largest community across all servers?
