1. Colony War Maps always have a second channel.
This makes sense so players that don't participate in Colony Wars (new players) can continue questing/farming/afking on Channel 2 of that map.
2. Those maps aren't heavy on the resources so the removal of the second channel will very likely not have any effect.
We will take following measure on next maintenance anyways: Optimization of maps related to Colony Wars to reduce connectivity (lag) issues players experienced on 14.06.2020.
Suggestion still has been accepted and we will try the removal if the lag issues on Colony War still exist after maintenance on 16.06.2020. Think of this as a backup-plan.
