I really like mass looting on servers that have it. It's a fairly small convenience, but the cumulative effect is significant. However, even though I like mass looting, I can understand why others wouldn't. Since it has the potential to alter people's behavior or the economy, maybe it's worth considering if it could be harmful to the server before I fully support the idea. Also, if it became a feature that you couldn't turn off, then that could be a huge turn off for a lot of players who want to feel like they're playing a not-overly-customized Cataclysm server. Though, in general, there are some features in the later expansions that would fit well on any server imo (xmog collections).
