After some examinations, only at MP oriented perk action (Ken Si) I saw some tiny irregularities, at least when it comes to attack and defense checks. All other professions have appropriate checks for their actions.
Instead of MC (or all nano skills combined) check, there is Attack Modifier one, which is wrong (after all, Ancient Knowledge buffs nano skills, not weapon skills).
Also, defense check is evade close/dodge ranged (50:50), which is in one word, weird. It should, of course, check Nano Resistance for defense.
Just wanted to point that one out.
