I'm not 100% sure. But last night i played US. Then saw most asian in EU i switch. My chars still there. Not sure but you can try.

Playing in US server sure lag even for me have you tried the EU server ? As for whether to buy this game or not, for me I had played a lot of MMO ranging from runescape , lotro , wow , rift and conan. I think any MMO needs to have a friend for companion playing with friends sure fun one. For me free 1 month gameplay and early access to the game can be justify with RM200 and further future gameplay that I'm not sure. Imo any MMO doesn't have long term or end game play style then I wont be satisfy about it.
    I like how ESO have good PvE mechanics like crafting and exploration , not sure about PvP yet. For me I will pre-order possibly imperial version if I can get some extra cash. Never played MMOrpg before ? then play some of the free ones to get the feel of dungeoning and PvE or PvP. Well cant compare Skyrim and ESO both are quite different in many aspect like few of the previous posters said.
