No, you're a single case. That's not a proof, that's an anecdote.
If you were to consider yourself a proof I'm wrong, then I could simply point at the OP as a proof I'm right. Which wouldn't be very conclusive, would it be ?
It did suck for small guilds without a strong core, yeah. The tighter ones had much less troubles, and at least it made for an actually active community when guilds were relevant.
