Proficiency: 1 point = 0.10% increased damage and healing
_______ Damage (They are all the same): 1 point = 0.17% increased _______ damage. Increases healing by 0.1%
these 2 stats seem to be different for healing. even though it says they're the same, the tooltips are saying something else.
for example
I used 3 of the strongest heals for druid. I was changing the stats of some blue pants I had (25.74) which should be 0.02574. I had some stat on them so I could see the heals without any modifier. Then changed them after and saw these changes.

i know they come out as minuscule amounts on tooltips, but tooltips lie
I did some quick math to see that the proficiency change would equate to around 3000 (give or take about 120), so those ranges look about right.
Even with a small positive change in proficiency, it ends up having quite a change to the entire heal calculation due to how the different modifiers work with each other.
Unfortunately, It's not easy to understand how a modifier works when so many are involved. I haven't been able to properly manage any of these, though I'll find the time to do so in the coming week.
To the best of my knowledge, you cannot multi-proc double attack. There is only the initial cast and the chance of a follow-up.
I have checked this, though only briefly and with quite low Double Attack (12%. Yay for low level Reincarnation access). I have never seen a double attack proc off of a previous proc. I have seen a back-to-back proc, though those are quite rare too.
Question about survivability / Concentration:
It says for survivability "Increases incoming healing and damage, absorbed by shields, by x%"
Does it apply for the shield you get from concentration?
It in fact does. Getting a healthy Concentration amount, then supporting it with Survivability is a good method for generating a strong self-applied shield.
