so far I have a level 50 bfg builded seraphim.. I used this guide to build it... so far I havent had any problems with this build but is it really worth putting Constituton on the skill list. for me it seems like a more dmg increasing skill like Combat discipline would be more effective since it decreases regen time for all arts and add combat art dmg, if u have enough regen per hit stacked the only dmg u do is combat art dmg, hence I think it would make a more powerful build. what I mean is that isnt it enough with the armor//warding energy skills? wouldnt more dmg be alot more helpful? im unsure if combat discipline stacks with the tactic skill tough, and would really like some feedback on that
