Actually, the servers are hosted in US, they said they will get more servers in EU too.
About WoW-killing ? I dont recon they ever said they want to kill wow and there is no need to. Blizzard is doing it pretty well with all the cash shops and said they want to kill WoW with Titan.
I am playing Wildstar for a very long time. My experiences ? No lags, I can even run it without lags or stutters on notebook. Their graphics and UI is very nice, I Love the mounts. When I first went to Battleground I enjoyed it a lot. Quests are not so linear, yea sometimes its kill x things but not much of those. The path system is very good, I have a settler and like it.
The movement is fluid, the sprint system is something new and fun.
Dont ever listen to trolls who say the game is bad or something like that. You have to try it yourself.
But is the game worth it ? Yes it is, its something new and not like boring wow but probably wont buy it for 2 reasons:
- I am college student of IT and I have no time (when I sleep, it is my vacation) + job
- I am playing WoW from patch 1.6 and I am so addicted to it that I cannot stop even I bitch about Blizzards shitty moves with Cash shops,etc. IT is still my number 1 game, fantasy, books, everything about Warcraft world.
Maybe I will but I recommend you try it and then make a decision.
Remember, it is still beta. Til release they will fix a lot of things, optimization is the last thing of making process.
