The EJ thread on the PTR version (which went live) of EM showed the DPS difference between 3.2 and 3.3 versions of EM was rather trivial. I've seen about the same results in my DPS. What I've done is swap blowing EM on every CD on my spam macro, to using it on my LB macro to get LBs out faster. I've also stopped using heroism before FS->LB and use it after CL. So the bigger part of Heroism is affecting my LB spam. I've only been doing this since tuesday, so I don't have any concrete numbers, but it seems like a DPS increase on the meters. But I've also gone from 2pc T8 to 4pc T9 on all my DPS. The shaman are hitting 5k easily on tank and spank bosses without heroism. Before I changed where I was using EM and hero, I was high 4.8-4.9k on tank and spanks.
