Hello,

I've finally purchasing Diablo 3 from Heroes Tavern for RM 218. Then installed on my PC and play

Im so noob about character heroes  and class as it totally different from previous Diablo. As usual, easiest class is barbaric, cause like fighter, just swing, swish, clang and get bad guy flying across screen. other character also try, but barbaric is easiest

by the way, i got doubt in for this Diablo 3

- does the game must be online when play? i found that my game lagging sometimes
- does the game smoothness depends on latency? mine always yellow. only sometimes red and green
- since mine is EU version, it always goes to EU server. How to make it permanent fix? like if i want to go to US server, each time i start play, it already in US server
- to keep latency up to max, which server should go? US,EU or Asia? if think logic, of course Asia because we all in Asia region
- inside package there's 2 guess pass of Diablo 3 and 1 guess pass for WoW. what is it for? 

need guidace to this so i can play it better

Sorry if this post had been mentioned but forum here really huge and hard to search for it

Thanks
