If they only cluster RvR:
+ More people to kill
+ More people for frontier raids (keeps, towers, relics)
+ More fun
+ No roaming around for 2 hours without finding anything
+ We get the least retarded people on excal (the hibs

If they cluster PvE and ToA:
+ More people to group with
+ Alot easier for new players to level up and actually enjoy the game and find new friends
Minus:
- The albzerg will be huge
- Possible lag and servercrashes (?)
- There will be alot more whine on FH
If they cluster ToA:
- Artifacts like Guard of Valor will be harder to get
But spawn and droprate is fixed in a few patches I think so I wouldn't mind.
I voted yes ofc. Prydwen RvR at the moment is not worth playing. But I wonder if Excalibur is really the right server to cluster with since it still have a pretty big population. But I guess they don't have any other choice since there's only 2 english servers

Prydwen needs Clustering
Excalibur doesn't
But what the heck, give cluster. Would prefer RvR + Old world, SI and Catacombs only. But if they decide to put in ToA too I don't mind. And just RvR is ok too :mezz:
