Hybrid Damge/Healing Razah Build

I usually don't post my builds but I was feeling proud of my little Razah-duder. This build comes out of the 4-man HM Areas to replace my Sousuke (in a Koss, Dunkoro, Sousuke, me (ranger) setup) but I ended up replacing Sousuke with Olias (MM) and Making this guy the primary healer.

Here he is:
[skill]caretaker's charge[/skill][skill]essence strike[/skill][skill]bloodsong[/skill][skill]mend body and soul[/skill][skill]soothing memories[/skill][skill]nightmare weapon[/skill][skill]protective was kaolai[/skill][skill]flesh of my flesh[/skill]

with a Sup Channeling and a minor Resto (he was originally going oto be a damage build with extra healing...I might swap those out but he works as is and I'm a dps fan). He keeps Kaolai up like an attunement and unless it's interrupted or (in 8-man groups) he becomes the primary healer (since I always use hench healers in 8-man areas they can't conform to the group build (7-hero group...7-hero group)...like I said, I'm all about dps) he stays at relatively full energy.

I've been really tempted to throw in [wiki]painful bond[/wiki] but it's worked really well so far...maybe replace [wiki]essence strike[/wiki].
