**** was very smooth, probably the best I have seen. LotRO was pretty good too.
On the other hand, Anarchy Online was a total trainwreck (all zoning transitions failed, so some of us were stuck in a shop for three days), as well as World War Two Online (spawning in upside down with your head in the ground, for example). So far STO, despite the extreme whining by some drooling idiots, is pretty good. A bit of downtime is to be expected.
