The higher your level, the more difficult it is for an illusionist to solo. Post 40 forget it as a source of xp. There are SOE executives on record saying .. In EQ2, if you can hit the mob, the mob can hit you.... meaning that kiting, root and nuke, and other EQ1 sources of caster solo xp are out. Considering this, mage class are at more of a disadvantage than other classes due to low ac and defensive abilities. Enchanters are the least of the mage class when it comes to soloing. It is possible to solo in the early stages of the game strictly because the mobs are so lame.
