I claim to be no expert with ToL healing since I play a priest and am currently trying to wrap my head around our itemization at this point in time, so I am looking to you guys for some help.
There is currently a druid in my guild
The World of Warcraft Armory who uses the battlemasters trinket in EVERY single boss encounter in the game. He claims to have no regen issues so I can see he would not use something like Tome or Bangle; but why not use something like Essence of the Martyr? I understand that static plus healing is very good for druids and since they took your nifty trick with rolling lifeblooms that are trinketed, use +heal trinkets are no longer as good as they once were.
I can see how he might use the battlemaster trinket over essence in sunwell due to the amount of raid damage that is being dealt. But as far as I am concerned, even a monkey can see that a 2 minute CD 297 +healing > 4 static plus healing and a 1750 "heal" when it comes to nearly every other fight in the game. Any light that you guys could shine on this topic for me would be greatly appreciated.
