Yes, the things I have worked on lately are earth shield uptime, riptide uptime, and I'll be focusing on earth shield and making sure I use all of my cooldowns as frequently as possible. I know, my earth shield is bad- worse on some fights, better on others. And yes, I am quite concerned over the discrepencies in numbers; any fight we three heal, my numbers tank. Garalon, I have a hard time hitting over 53k hps- my holydin hits 70-80k. Blade Lord, the constant spread kills me, the movement in phase two is not a strong point.
Re: Earth Shield - it and CD usage are what I'm focusing on this next raid lockout. The last one I was concerned with learning new fights and mechanics, and definitely wasn't babysitting my shield as much as I should've been. I wasn't as familiar with the mechanics, and tend to be overcautious on unfamiliar fights, 'saving' my CDs for when I might really super need them.
Water Shield glyph is something I switched to at the suggestion of this forum, but I admit I haven't paid much attention to my glyphs; honestly, I don't find our glyphs to be very helpful in any given fight. Strictly speaking, I should probably unglyph TC as I rarely use it, but my other options are chaining - no thank you- HST is not terribly useful in HoF, might be good for Lei Shi... Riptide Glyph can go die in a mana-slurping healing-stealing fire, and SWG glyph, again, has limited use.
I could do better on HST, but it isn't a priority, as it doesn't do much healing; I'm not saying it's -wrong- to use it on CD, certainly that's beneficial, but I think right now I need to focus on keeping my ES uptime higher and find ways to use my CDs more.
As far as Ascendance, I planned to use it more than I ended up 'needing' to in Terrace, and I have a hard time with it in HoF due to the spread out and run nature of so many of the fights. I love the ability, but damn, it's hard to fit sometimes. Same thing with SLT.
And for Healing Surge, it actually is better to use than GHW until you get the 2 piece tier bonus, which I do not have; it is higher HPS for approximately the same cost as GHW, according to the math - here's a thread on it on Plusheal if you're interested!
So, to sum up, I'll look into my water shield glyph usage, try swapping out UF for PE, work on upping my earth shield (which gets especially low on Garalon, I usually toss it on the pheromones kiter who stays out of range), maintaining my high riptide, and try to fit every CD in twice per fight- easier without PE in the mix. Also try to get HST out a bit more, but it's a pretty insubstantial amount of healing, compared to the +healing on my ES target, and even the healing done by ES itself.
