Guild Wars 2

Dear Arenanet Staff.
I have some questions regarding overflows.
Overflows were, as I understand it, created as a gateway for people to join the main maps in a timely manner without blowing up servers. The idea is great and wonderful.
However. Overflows has become more than just that. They are a way for people to earn money (I.e Karka Queen Farming) and most importantly, they are a “private” place for large groups of people to gather to do major events, such as Tequatl and The (new) Great Jungle Wurm (love the design of the battle btw.).
I am a member of the European group of guilds, TxS, in the guild THS. We are using overflows to fight the Wurm, because it’s simply not possible for us to get a mainmap “to ourselves” (we’re waaaay more than 150 people, so we could fill up the map several times). The reason we want the map to ourselves, is because we can get people on TeamSpeak, providing us with communication and cooperation needed to kill this boss.
Here is the problem. We cannot fit as many people as we’d like in there. It’s a given that there must be a cap. The problem is that the cap on the overflow, is lower than the cap on the main maps.
This becomes somewhat of an issue.

Desolation server killed the Wurm recently. They told us they had atleast 50 players in each of the zergs. Therefore that had atleast 150 players in there.
On our overflow, we cannot get those numbers. The three zergs average around 40-45 players, before it’s hardcapped and we can’t get anymore in.

Is it possible to raise this cap a bit, for the overflows? Or do you have any other suggestions as to our “problem”?

Sir Gophlin.
