Rotation of maps
Not sure I can see how this could work. One week you have Alpine and plenty of players who know what to do and where, then next week you have Deserted BL and almost all the action will be in EB.
Since match up s are decided weekly, and ANet seems to be trying to mix these up a bit again, you’ll have people who will play/won’t play and a ton of complaints about “We would have won that if we had the right map”.
You can’t make match ups a 2 week duration without making things even more stale – so I seriously doubt a rotation will be as helpful as you might think.
