When comparing the old Enhance profile (downloaded 2013-05-30) against the newest one, i found out after testing 15 million dmg on raiddummy, 10 times, with ilvl 503, that the old one was doing an average of 87k dps, while the new one only did 81k dps.
It felt like the new profile didnt prioritized lightningbolt as much as the old one, and maybe thats why it has lower dps?
