Skolas is a chore, but can be fun. My biggest gripe about the whole thing are the garbage rewards. If you are lucky enough to get one of the elemental primaries, you only get 2/3rds of a weapon and the weapons are just plain bad. The rest of the rewards can be had on the 32 (armor core) and 34 (weapon core, etheric light, possible elder cipher). There is not much motivation to do Skolas. VoG is actually fun, so I would rather do that for no rewards at all than Skolas.
