I think they get it (after some urgent stress testing atop ToO!) but the display does not update. Having said that, we were a trifle busy at the time to check logs etc especially as a CJ popped around then. What have others seen?
I've seen this happen not only on healing classes, have sent and waited to see the bar go up for at least 10 seconds when this happened and nothing. It's either a major updating fail in our screen or it just doesn't share the power.
I have rarely seen a big change in the other's bar, but have heard afterwards that so and so appreciated the boost so they must see it.
Also, like equipment with higher "Incoming Healing" to receive a bigger share of the morale transfer, are there any factors that would effectively reduce the share of the power transfer they receive? I doubt it but am curious.
Accounting for the lag time between sharing power and seeing the number go up, the share power issue seems to have decreased significantly for me. The huge amount of will/fate/icpr minis and rks have now has also helped. I've noticed this on my own newly 75 mini, that even without an LM in the group, power is not as big an issue as I thought it would be.
I find cappies are frequently much more in need of power than main healers are, the longest boss fights aside. Since keeping hunters, burgs and champs blue bars filled is easy, and shortens fights as they can keep up the big dps skills, I like the balance now. Of course, this is just raiding with my kin and I never pug. I'm sure mileage varies!
I reckon Captains are probably now #2 on my list for recharge needs and certainly I find that my cappy runs out of blue faster than I recall used to be the case, probably because the stats are now so minimax.
