Communication and coordination is key. Plus, multiple streaming their screens.
If no one is talking it’s going to be a mess. If everyone is talking it’s going to be a garbled mess.
So respect, having a lead, call outs, positioning.
Done this plenty with multiple clans with great success. Mostly were 2-6 person clans who didn’t want to join each other to lose building ownerships. So not even full clans filling up a server.
The best players are those that are patient, they communicate, respect others and lean into the plan.
But, see that is a lot of work just to zerg. And not being able to help repair or see the allies event logs goes a long way to a better back and forth raid. Alos locked vaults for FOB. having to have those seperated makes life harder on zergs. So again, not a perfect solution, but any speed bump to billy zerg large coans is a plus in bapance for the smaller, and dare i say less toxic, clans.
