Level 68 SK and a 62 Sham with journeyman 1 mercs. Assuming I can not obtain outside help (not likely but plausible), what level should I begin to get my epics?
The items themselves have required levels of 65 & 70, respectively, to keep ambitious players with friends from accessing them "too early". I think going ahead with the quests until the difficulty actually stops you by killing you is entirely reasonable.
