So I know I haven’t played mine much lately nor really talked about him, but there was a new guide posted on the forums which has sparked some good discussion as well as a mention of an old guide being updated as well.  Here’s the link to the recent guide by Cithryth as well as the link to Elborigorn’s guide.  Cithryth primarily focuses on a grouping/raiding Captain while Elborigorn’s is a bit more inclusive to include all the roles a Captain might have to fill.  So, if you have or are leveling a Captain both treads are good reads for ideas a build suggestions.
