I have just acquired my [Darkmoon Card: Greatness], which gives you a choice of +90 AGI, STR, SPI, or INT.

Naturally speaking most hunters would take the AGI.

However, with the Careful Aim talent you get a 100% of your INT as AP.

With my current gear setup I would get 4443 (36.41% crit) DPS fully buffed with the AGI card. I would be getting 4449 (35.22%crit) with the INT card.

Unbuffed the #'s change to 2154/23.79% (AGI) 2174/22.71% (INT)

I then changed the Spreadsheet to get the best in slot items.

Fully raid buffed the AGI was ~2 DPS better then the INT one. However, take the buffs away and the INT one was ~12 DPS better.

So my theory/question is that the +90 INT card is better then the AGI card for those that have 3/3 points into Careful Aim.

Thoughts/Feedback appreciated.

The spreadsheet already gives you the most scientific answer you'll get. Both options give you the exact same amount of AP, so the difference is crit vs. mana. If you aren't running low on mana (as would happen in short fights with lots of mana regen buffs available) then AGI would be better. If you find yourself running low on mana fairly often, then the INT card will lengthen the time before you have to resort to Viper, and it will result in more mana recovered over a set period of regen for those things that are based on a percentage of max mana.

You'd have to evaluate which situations you actually find yourself in to get the answer, although it's worth considering your other slots as well. By that I mean if you get 90 INT on your trinket, then you can perhaps use leather items in certain slots without worrying about lowering your mana pool. But if you aren't in the market for leather items, that wouldn't really be much of a factor.

This thread does not need to exist.

It's a legitimate question, and we shouldn't shut him down for it.

It's not a bad question per se, but it's quite easily answered with the spreadsheet. Easily placed inside of another relevant thread at least.

This means it's a bad thread.
