Question about Astrologian and buffing in 8-man raid.

[Jijifli]

But the buff weakens to 10% for a balance AOE, but the enhanced version increases the cards by 150% potency. Isn't that more effective on someone that knows what their doing?

It doesn't enhance it by, it enhances it TO 150%, so a 50% boost. That means that it would be 30% more damage, not 50%.

Spreading cuts it down to 10% each, but consider that you hit 4 dps (40%) and tanks who are still dpsing (60%) and if healers get involved (potential 70-80%)

As we can see, even IF it boosted it by 150%, it can still do more spread.
