I can completely understand where Elhron's coming from. If you're not having fun, you should be able to change your circumstances. Our server is dead, dead, dead. Imagine if on Argent Dawn, there were only 18-25 people in Stormwind at prime-time hours.
The super-server merges should alleviate some of the issues, but like I said before, I can't blame anyone for moving to a guild where they're more active and having fun doing things in it.
