Divination & Math - Is it worth using in dungeons? Only in specific situations?

[Seraphor]

Honestly with a 3m CD, Sleeve Draw needs to fill everything up like it used to before. Randomize the 3 seals gained so it's not always max dmg.

This sounds good, in fact...

Sleeve Draw:
Gives you 2 CD free Draws (3 is unnecessary if you’ve just used one, and less Draws to try to weave)
Generates 3 random seals (thus why only 2 Draws are necessary, no matter what seals you get, you only need 2 to fix it)
Reduces the cooldown of Divination by 60s. (adds in a Divination buff via a reduced cooldown, but only from level 70 onwards)
