I know some folks are going to disagree with me here, but the latest beta was a major improvement to the WvW experience.
During the last beta I've been able to play in an environment which is not controlled by universalizing guilds with ~2500 members filling up the server (I'm looking at you Dragonbrand). It was a really nice change not to be dominated by the politics of guild numbers on the server making demands on the premise they "own" the server, have x million members, and nobody can tag up without their approval.
Moogooloo had an overwhelmingly positive and productive chat in-game with very little toxicity. Most folks were sad to see the beta end, and not because of the bonus. Moogooloo was a ragtag group of guilds coming together and we collectively shut the enemy down (check the scores). It was absolutely hilarious to wipe a large guild from Dragonbrand over and over until they just ran even though our numbers were far smaller.
In the antiquated system, which has existed in WvW, quantity of guild members dominates the quality of players in that server. This beta proves that quality and skill level supersedes quantity. The beta has also eliminated the behind-the-scenes politics governing who is allowed to tag and how to throw the matches to manipulate tiers.
I'm a guild founder, and I'd like to play with my members, but it's really hard when the server is full due to 2k+ people from another guild joining my server and filling it up. I think most of the negative feedback about the beta is coming from those who want to keep the current system in place so multiple guilds, which they control, can be in the same server and that is unfair to the greater community, whether on the same team or not.
I believe GW2 is about community building and inclusiveness; even in competitive game play. I personally feel this last beta was a step in giving freedom back to the individual player to enjoy WvW by selecting who they want to ally with.
Again, I truly think the direction of the World Restructuring is in the right place and hope to see it finalized soon after the next beta.
Best,
Ghost
