Executioner Test - ~2H20
The tests were run with 3 mods working at same:
Procmeter - counts procs only when it gains
Procwatch - counts proc when it Gains and when it Fades
Uptimemeter - tells you % of time it was up and runing
I made for tests of ~35m each, all 4 in battle ST and only auto-attack.
Test 1 - only 1 weapon(talon 2.7) with Executioner used and in MH
Test 2 - only 1 weapon(talon 2.7) with Executioner used and in OH
This test also includes the hit from my unarmed MH
Test 3 - MH(dragonstrike 2.7) with Moongose and OH(Talon 2.7) with Executioner
Test 4 - MH(Talon 2.7) with Executioner and OH(Fist S2 1.5) with Mongoose
Dont have a slower weapon with mongoose to put on OH to this test, but the fist also dont have the high haste proc from dragonstrike.
My tests show that the uptime is around 9 minutes (average) in the 35 minutes of the test.
the PPM is the same on MH as is on OH - 1.8
(except on my first test that is 1.4, this may be cause of less Flurry uptime on this test for sure)
Im not a theorycrafter by nature by is pretty obvious that it doesnt matter in what hand the weapon is MH/OH to have the same PPM.
u can see the test screenies for yourself and debate freely.
PS: i dunno i to get the Combat logs u require, but hope this helps a bit.
Edit: My build is 17/44 with precison 2/3 and WM 2/2, also i was on my crap PvP gear for more HP
