Positive reinforcement works just as well, when we were on T12 we could of really done with hitting 4 Bennus but were a couple of % short. With reminders throughout P2 [keep pushing dps on the boss guys] we managed fine.

Saying as such though - we recognize during 'training' there is a natural dps shortage. Before you all move to mechanics in auto mode and deal with them the same every single time your DPS won't be the best it can be - DF, or PF groups will also have a naturally lower DPS than a static because they are not hitting everything at the exact same time in the exact same way they have learnt to maximize their dps.
