Raid DPS Contribution is IMPORTANT

, a big nuke every 90seconds.

The funny thing about this is even by the standards of stone 4 the nuke is a DPS loss. It costs you 4 GCDs to use it since you need to heal 3 times to have it available and the nuke itself is also a GCD.
It'll be nice for pugging, but with how healing works atm it's pretty uncommon to need even 2 GCD heals in 90 seconds let alone 3 so the most realistic case for it is it'll be about DPS neutral, slight loss or slight gain which is really laughable to have over a 90 second span. Imagine 2 of those heals in that 90 second window was necessary, the potency gained would be like if you got an extra cast of stone in those 90 seconds. Sad.
