Hear me out first.
EBG stays as is. The Three Teams battling it out.
But there would be 2 Boarderland maps for your faction (I am calling them Factions in this discussion, but we talking about Servers/Teams/Links/Alliance/whatever)
If you Red Faction for example, your Map Selection would look like this:
*Red vs Blue Boarderlands
*Red vs Green Boarderlands
These two Faction Boarderlands maps would be redesigned for a North vs South approach with balanced designed for Structures, rather than how they currently are.
The goal here:
To designed a more interesting Boardlands map gameplay that would be equally as fun and rewarding to stay heavily populated as ETB normally is. Less Borderlands maps at once, will also help populated these Boarderlands maps.
Three Faction battles still will be the norm in Eternal Battlegrounds. Right now Boarderlands barely are populated on a consistent bases for most servers to warren it staying the Three Faction design that it is now.
