Take this as you will, as specific healing comp etc has a huge effect on what we are capable of doing, but here's some logs for people to pick through to compare your jab x2 Uplift (old playstyle) vs my SCK rotation. (this ends up being more about spirit vs throughput because empress I jabbed a lot this week)
For reference, I am dropping to ~12k spirit based on how raid went last night, I MIGHT drop out of more later, but i'm doing it in small batches just so I don't totally screw my regen over
I'm going to use Gnorrior as an example since I can easily find his logs, this is by no means me saying anyone is bad but just a flat comparison to show differences:
Affinichi: 132,499.4 HPS 51.27 mill healing done over a 6:25 kill
Total Jabs: 0
Astralos (Gnorrior): 111,135.1 HPS 42.89 mill healing done over a 6:24 kill
Total Jabs: 56
Affinichi: 82755.1 HPS healing 71.13 million over a 14:19 kill
Total Jabs (and I had way too much mana lol 3shamaan this week): 100
Astralos (Gnorrior): 73375.7 HPS healing 58.2 million healing over a 14:20 kill
Total Jabs: 92
There is value behind each playstyle, each set of spirit values. I've had way too much mana on some fights (Grand empress last night I ended with way too much mana) and other fights not so much (Garalon mana was very tight, but I did more healing).
The tradeoff here is basically more regen = you can spam more abilities (If you decide to jab jab uplift you can do that even more effectively here with more spirit as well if that matters) vs more throughput, but more time sitting there doing nothing.
Is there a right or wrong answer here? Probobly not. It goes back into one of those "play what feels right and do what you do" as for the most part, the differences SHOULD be marginal.
In an ideal world, as far as snipe healing is concerned, more throughput stats vs regen would allow you to burst higher with jab jab uplift to snipe quick heals, however with how few RM's are out it's not entirely practical or a very solid way to heal around sitting there doing nothing until a) you have your TFT Rms rolling and b) damage goes out.
What works for me doesn't always work for you. As far as me having TOO much spirit? I don't really agree. As we become more comfortable with mana changes then yes I'll pull back a bit, but I don't feel like I am doing anything more wrong than you are
Keep in mind that Jab for whatever reason still only costs 9k mana instead of it's increased mana cost to 11.5k like it was supposed to be hotfixed last week with the other mana cost increases, so what you are healing with isn't necessarily intentional as far as regen is concerned. Since JAB's mana cost isn't technically increased, it will appear to be more efficient than your other spells as those cost ~43% more than they did prior, and jab remained the same. This is a bug, and NOT intentional.
