Most updated in bg numbers
BOA weap + eyepatch - 32ap, 2.22% crit (due to agility + crit from mace) , 5 haste, 8 hit, weap damage 88-107 (359 ap)
Riot Stick - 0AP, 1.9% crit, weap damage 93-117 (327 ap)
Note: I only used offensive stats in there
Riot stick does do more damage for mangle/shred/ melee. However, it isn't game breaking, you lose crit and ap. Overall your DPS wouldn't be affected really, it does change your playstyle tho which could become more useful in certain situations. Also at higher APs riot stick becomes less % beneficial, which is why i like crit stacking if you are gonna use riot stick.
Also, im so slow at making this guide lol. idk how u do it bend... ill work on it some more tonight, still 1/2 done
