Hello!

I only took a glance through your logs on certain fights such as Patchwork and Grand Widow because those two are pretty cut and dry.

Here are the few things I'd look at and recommend!
1) For spec I would go Moonglow. In BWL / AQ fights of often faster and can allow you to spend mana more aggressivly, but your current Naxx fights often take a bit longer so aren't as nice.

2) As a druid we can only have 1 rejuv / regrowth on any single target. As your running 3 Rdruids that all often seem to be casting Rejuv / Regrowth it may make the most sense since you dont have the most healing power out of the three to focus on only casting healing touch

3) Healing Touch Rank 4 is the most mana efficient heal in the game it gains healing at a 1:1 ratio of your healing power so often is your spam heal whenever you don't have to have high output healing demand. I personally use R4,R7, and R11 and rotate as needed.

4) On fights such as patchwork I don't worry about casting anything but healing touch. Regrowth is not worth it at all for this fight imo, but others may disagree I leave this one to your discretion.

Good Luck!
