Same. I'd like to get a definitive answer with numbers to prove it, feels like all anyone wants to talk about it making huge opening parses on 2 minute combat dummies and Faust :p
If you pop your CDs on-cooldown, within reason (ie. you might not want to waste cooldowns when you're failing to proc anything on split shot, but wait until you get a proc or two along), then you certainly arn't going to hurt your DPS. Nonetheless I'd like to see some proofs to whether that is the best approach possible.
