Int gems for BM hunters?

On what planet is an Int gem BIS for BM hunters? It makes no sense to me. I mean agi / AP / crit gems I could understand…but Intel gems?! LMAO

If you are optimizing for a fight in which you run out of mana, increasing your mana pool to use more shots can sometimes be a more efficient use of stats.

Make sure to set up the optimizer for the fight length and buffs/debuffs/consumables you will actually be using.
