hi.
also, how is the Riot Stick even an option, since you'd have to give up the eyepatch to get it?
that extra 8 AGI (16 AP) and 8 hit wins...
Probably just a comparison. Also, what matters is the DPS, as only a fraction of AP is converted to DPS (unless, for ferals, other abilities scale directly with AP and not with DPS, like hunter explosive shot).
In battlegrounds, eyepatch and the BoA mace alone adds up to 16 agility, or 32 AP, [and 15 agi, or 30 AP at level 20] which adds about...
32/14=16/7=2+2/7=about 2.29 DPS [30/14=2+1/7=about 2.14 DPS at level 20],
making the BoA mace+Eyepatch worth a little more than Riot Stick in battlegrounds when the BoA mace scales (meaning mace Weapon Damage and Speed gives about 23 DPS, instead of 21 at level 20).
Not to mention a trivial way to hit-cap with eyepatch+rune, versus (hogger pants)+rune or (worse for glass cannon) drakewing+rune.
At level 20, Riot Staff comes out ahead by [taking into account eyepatch as well]:
(24.7)-(21+2.14)=(24.7)-(23.14)=about 1.5 DPS, or about 7*1.5=10 or 11 agi worth of DPS.
[Assuming my quick theorycraft numbers and estimations are consistent with live].
Oh, and 15 agi also adds about 1.5% crit chance at level 20 (1 agi=.1% crit at level 20), if one believes it matters.
