ZEM/Zones for 16-20 for duoing

[veejur]

Hey guys,

Been duoing with my wife (me a necro, her an enchanter) in Kurns until we hit 16. We're trying to duo instead of just group to make sure we can still make progress exping when groups are full in the mid levels (which has been a major issue on my monk).

I wanted to ask if anyone knows some zones that appear to have good ZEMs that are duoable around this level (16-20ish). I know Unrest and Befallen have listed good ZEMs but these seem like they would be difficult to duo at our level. We're considering oasis or LOIO but I know at least the "classic" ZEM is listed low on both zones.

Any advice for good duoing spots at this level for casters?

Thanks!
