So, I'm partially slotted with IOs. SOs rest of the way, and I.... tanked Lord Recluse in the STF with my PB.
Essence Boost + Lightform + Conserve Energy + Dwarf and the only outside healing I had was a wonderful trollers o2 boost spammed on me.
And I successfuly sustained tanking him. Granted I died close to everytime lightform wore off, but restore essence and lightform were recharged by that point so when he ran off to the group attacking the towers, I would rez, click click click dwarf taunt and I was back in business! Truly awesome.
Haha, congratz. Who needs a tank, eh? 
I would've killed for a tank rofl.
We had a brute that didn't have taunt, so he couldn't kite LR.
Realizing I was the only one with taunt, and having years of tanking under my belt (I have mroe tanks than any other AT), I had to try. 
No problem, hope you have fun with it.
