*sigh*
there's actually a history with that build...
Before MotU came out I wanted a Shadovar, based on my several year old PnP Monk of the Dark Moon (named Kodara). Andoris and I worked on that one...she was 12 Wizard / 2 fighter / 6 monk. Then MotU hit and she couldn't keep up (thank you insane amounts of divine punishments). The build was scrapped and I went to work on completetionist. I always wanted that build back.
Andoris kept refining his PM, being a good DC caster was something he wanted and he put the work into it. When the original Pale Master Guide was no longer being updated, he decided to write and maintain a new one; hoping to help others avoid his painful learning curve and endless testing.
Harper came out...I could have my Shadovar back. This time since we had years of playing and all his research on PMs and abilities we could attack the build head on and make it viable again. (White boards were damaged in the process...you should see the picture of it)
We started with the
Shadovar Infiltrator. I still play her (modified) and that thread we noted the successes and the issues. As I played more and went through feedback he had a baseline to refine it into his Blade of Velashoon. Since he didn't need any more past lives, he skipped the trapper because the XP wasn't needed and focused on bringing out a bit more red name DPS, a worthy goal since red named DPS on a caster consisted of major kitting and 100 SP pots.
Those builds are not the markers for the game not being balanced. An unbalanced game would allow for DC caster to have excellent red name DPS without having to dip into other classes or pile through resources. If you want to "solve" a class weakness you have to focus on overcoming that.
That's not unbalancing that's creativity.
