At level 60 Scholar I think the least useful of our new abilities is Emergency tactics (yes even less useful than Dissipate) The double heal doesn't make up for the loss of shield in most situations and in those oh shit moments adding an extra button press to the mix seems detrimental rather than useful.
I feel I would be more inclined to use it if it made the next shield skill turn into a full heal and be instant cast, this would feel more like an emergency button and be a lot more useful.
It would also help to supplement lustrate and Indomitability so it becomes a choice between mp or aetherflow, feeling like as a so called strategist we have more options available to us.
But in other news also fix dissipate, at least increase the heal potency/ make the next pet summon free / lower the timer on pet being away.
