wraith or lich are just usefull if u DO something ^^
but i dont think your suit is that good, that u allready got LRC + Luck + Manareg/LMC and cast all the time like a mage
arty drops ... no one could say how arties drop for u ... its totally random
but i red somewhere that new chars get a higher chance for arties ^^
but dont think arties will pop up every day with your HH pack
when i was there with my HHs i often had to wait until someone came on with a GD or something else who can tank
i couldnt solo anything with my archer/tamer
(but thats just me)
