Yes, server location has something to do with ping, as does your own internet.
Yes, different servers would give different ping options, however, during Alpha/Beta, it makes no sense to shell out the extra expense for additional servers, especially when testing populations tend to be so much lower.
The game does fully intend to have an EU server on launch. They have said the launch plan was for 1 NA server and 1 EU server, and then other servers may be added as population demands dictate. That is normal for a game.
Many people play this game with over 200 ping and still manage to excel at PvP. The overall game latency is not actually that bad, the biggest problem is trying to do things like dual client on the same system, and eventual stuttering after being online for awhile.
Luckily, the dedicated PvP world isn't even implemented yet, and that's where the hardcore PvP types will probably focus their attention.
As for a CM responding, Arcahem is the only CM, and he might respond, but this has been answered several times in the forums, so I can tell you right now, they already said NA and EU server upon launch, but probably not before.
