Yes, if you push CON it's not bad at all. With low or normal CON it might work if you rest a lot.
As firkraag888 said draining works nicely on rogues as long as they are able to attack, because usually they deal quite some damage per hit which leads to good regeneration numbers. And besides that: Draining doesn't need INT or MIG like other healing does and also doesn't work with survival so you can focus on stealth or mechanics. So, all in all it's a good approach for a rogue with low INT and/or MIG.
I played a max MIG, max CON, 1 (!) INT rogue with Tidefall and RUnner's Wounding Shot as my main attack ability. He had no Veteran's Recovery because of 1 INT and also no Shod-in-Faith because of that. Still he stood in the front line and was used to operate behind enemy lines with Escape/Shadowstep. He was surprisingly sturdy after the early game was done (where high CON doesn't have that much impact but the low starting value has) and after I got Tidefall. He was a good rogue: low babysitting compared to some other rogues and great damage because of Tidefall and RUnner's WS combined with 1 INT.
If the rogue has high INT and MIG though I would def. recommend Veteran's Recovery and survival over draining (or better: in addition to draining). THis even works when he's disabled or running around.
By the way: a great sturdy rogue who needs no babysitting after the first levels is one with a bashing shield (for the strikes - best is Badgradr's Barricade), Veteran's Recovery and Weaon & Shield Style. Retaliation also works with Deep Wounds and here also Riposte makes sense.
The class that profits even more from draining is the barb - as long as he can hit several enemies with Carnage (because draining works with Carnage). He will leach from all enemies he hits. Barb + Tidefall is a lot of fun, also beause the wounding negates some DR-problems with Carnage (34% damage malus).
