Judging from how popular the Asian marketplace is compared to American markets such as jsp, you should not only be able to find sufficient dueling but even more than you have been here in the US. the problem is whether you can speak the native languages (mostly Korean or Chinese).
Just to break this down for you, there is like well over 10,000 people looking at any single Asian marketplace for D2R at any given time each night
Jsp is down to ~300 each night for NL and Ladder, probably with overlap so thats ~500
Asian community is way more active and into this game than Americans, period
edit/ the other problem is that Asian players have completely different rules than American PVP especially for gm duels. It's gonna be completely foreign to you for a while. In particular, the way they are allowed to stack poison damage is pretty wild and will take some getting used to.
