After testing Minor Slayer myself as well as watching and looking through other people's research, it has become very apparent that Minor Slayer (5% to Bosses) is underwhelming and, in most cases, a DPS loss. Given that it comes on what is supposed to be BiS/Progression Trials gear, this needs to be reevaluated. Both Minor Vulnerability and Minor Berserk are 8%. I believe Minor Slayer should be bumped to 8% as well. This would bring it in line with other buffs/de-buffs
Likewise, the Moondancer 5x bonus is also underwhelming. While Alkosh, Twilight Remedy, and Lunar Bastion all provide useful bonus, Moondancer is not useful and extremely hard to control. Please, ZOS, rework this bonus. Maybe something like 374 Spell Damage and 189 Recovery 100% of the time (rather then more of either)? Something to make it pop as it is supposed to be progression gear.
It would be wonderful to see adjustments to these make it into DB! Give us End Game PvE'ers sets to work towards that matter!
While I'm on the topic, I appreciate the time and effort that went into rebalancing Scathing Mage. The set final feels right; more DPS then TBS/Julianos but not out of line with what is expected for Endgame gear.
