Once you get to Heroic level dungeons and beyond, the warlock is one hit away from death as well. Better to let the tank put a sunder or 2 on the seduce target mob first, as the succubus can always go back and receduce the mob. Also of note, at your gearing level for entry heroic dungeons, your succubus only has enough mana for about 3 seduces. That actually may not be long enough for the fight. Letting the tank hit the mob means after succy is OOM, she can dish out a little dps (with LoP off) while regening a bit of mana, then receduce the mob again later.
