If no BLM I use it. I love it. My CNJ is only 34 but even when I run with a FC BLM friend we chat and each sleep a different mob to make it even faster/safer. It is just another tool to be used when appropriate. ^^ That being said, I have had a few times where there was no BLM and certain pulls have a lot of damage fast. In those cases spam curing has been better and safer than trying to sleep first and then cure.
