I run a 3 person premade - Mnk Smn Whm. I'm the whm. We go up against blm comps all the time. I have a 95% win rate overall. The last time I got slept more than once (Can purify the first one) was lets see.. Oh yes, it did happen one time, over 150 matches ago.
If you just strategize and load up your group with hots and hide while they run in and pummel the black mage instantly, the black mage might get 1 sleep off on your dps, which they purify and then the blms dead 5 seconds later.
Black mages are incredibly squishy, as a healer you just hide and have your team destroy them before you come out, if you need to you can pop out for a split second to esuna then hide again.. Sleep is a gimmick strat.
Double summoner however, now thats a scary comp.
