ROE and ROg used to have great guides, most of the veterans left RO altogether though, so the guides are outdated.
BTW, if your guild is the kind where they're really serious about woe-ing: They have perma pure INT clowns, FS profs, INT/VIT wizards, WS buffers, FCP creos, double SLs, who will always be online for woe, then you might as well use a Spiral LK and stay in precast pack =X
