In the char template guide all of the mage temps have wrestling, anat, and eval. I read in the anat and eval guides that the defensive bonus is active on the server so wouldn't having wrestling on any character that also has eval and anat be pointless? Maybe i'm forgetting a benefit of having all three skills, it has been 10 years since I quit.
Wrestling and (Anatomy/Evaluate Int) both provide a defensive benefit reducing the chance to be hit by a melee weapon and lowering the chance to have your spell casting to be interrupted. The added benefit of the wresting skill is the ability to interrupt another players casting with a wrestling attack during combat. Otherwise you can choose which of the skill sets (or both) that suits your intended play style. Most PvP'ers would take all three, while your average PvM style player would only take one. Anatomy / Eval aside from defensive wrestling also provide large damage bonuses to melee and magical attacks ergo the inclusion in most templates.
