First question: I've read here and other places that critical hits add on average about 50% damage threat over a regular hit for the same amount. I wondered if anyone had any links to tests verifying this (by empirical data from tests or whatever possible). Not that I don't put faith in it being correct, because it feels very much like what I've experienced.
I've tried testing it a little, but haven't really come up with any solid way to verify that's how it works, which is why I ask.
Second question: Playing a fury warrior alt, I don't really have access to all the excellent one handed weapons available in Blackwing Lair and now Temple of Ahn'Qiraj. I've been considering trying to get the Sand Polished Hammer from Ossirian, which has good dps and stats (for my level of playing field). But the hammer is very slow compared to traditional off-hand weapons. So I'm wondering how much impact a slow weapon in the off-hand would have.
The first point I look at is rage gain. If rage gain is based purely on damage dealt, the only difference would be less chances to gain rage from Unbridled Wrath, which I have ditched in favor of Booming Voice, so that would be a non-issue. Some people seem to hold to the thought that rage gain has a flat one rage per hit in addition to the rage from damage, in which case I'd lose a little rage, though hardly enough to impact my fights much I'd think.
The second point would be Overpower opportunities. Here the slower weapon would obviously lose out, but on raid bosses Overpower lights up pretty much all the time as it is now, so I think I could live with a little decrease in this area.
So, after the rambling the question would be: Are there any additional downsides as a warrior to having a slow off-hand?
I do agree that the swords from ZG are great for dual weilding. Exellent stats and decent dmg.
I use an Edge of Chaos main and a Deathbringer offhand. Deathbringer is 2.9 speed and pretty much your slowest Offhand you can find. I also have 4/5 in offhand dmg talent for the extra 10% offhand. I also have 3/3 improved Heroic Strike. After a charge I never seem to have a problem with constant Heroic Striking and even a Bloodthirst every 6 seconds. After I have my shouts off, rage seems almost endless if you have a decent crit%.
As far as overpower, I'd rather stay in zerk stance to try and keep flurry going instead of dancing to get that overpower. Overpower, in my experience, is more useful to a 2h warrior than a fury one.
I am worried about flurry in 1.10, but I don't think it will be too horrible on a fully buffed raiding warrior. I also think subscience hit the nail on the head with the benifits of a hard hitting slow offhand. Building rage, not consuming flurry hits from your MH and hitting hard are the things you should be looking for in an ideal offhand.
Bottom line, +hit and +crit are your main stats as a fury warrior. If you keep that offhand swinging fast and flurry up, rage shouldn't be a problem with a high dps offhand as opposed to an offhand that is fast with stats.
