what class combo do you suggest?

[Izmael]

Enchanter - druid: snare + charm = easy quick safe exp, great group appeal at higher levels
Necro - necro: easy quick safe exp in undead zones, no group appeal
Troll SK - troll shaman: fun, lots of places you can go, few things you cannot kill, good group appear
Enchanter - enchanter: different and fun (did that with a friend, had a BLAST). Gets you to 55ish in no time. At higher levels, two encs are redundant in groups, but a single enc has great group appeal of course
Iksar shaman / iksar monk: something just sounds right about this setup
