We geared out four tanks with 4/9, then opened up loot to rogues as well. In retrospect, we should have geared out 8 tanks with 4/9 first.
4/9 Bonescythe is a big DPS upgrade for your rogues, but realistically mage DPS outperforms them on most fights that matter anyways. It sucks for rogues, but hey, those are the realities of the situation.
Where do you find your mages? We have 5-6 rogues pushing 700-760 DPS, and no mages even close, even with the best PvE spec available.
We will probably hit the 4H with about 6 wars in 4+ pieces with our 2 MT's in 6/7. Atm our primary MT is at 6, secondary MT at 4 (he will be up to 6 when the pieces he needs drop). Otherwise we have 2 more wars with 4 now, 1 with 3 and 1 with a single piece. Some pieces have been opened up to rogues but I think the idea is to have at least 6 of them with the 4+ bonus by the twin emps. We should be hitting Gothik and Loetheb harder now that we've got Thaddius figured out and working for us.
Our three main tanks get priority on T3, then the rogues get a go at it on roughly the same basis as the secondary tanks. DPS warriors got co-priority with the rogues, more or less, on T2.5 in AQ40, so T3 is hands off for them until afterwards.
Let's just say that our BWL warrior loot is extremely poor. During the probably 8 months of farming the instance, we have only geared up 2 full T2 warriors. So naturally in order for us to progress end game wise, we need to gear up a couple of selected tanks first.
Not to derail too much, but... what loot system are you using where (presumably) rogues have been seeing fat days in BWL/AQ40 and warriors are running around in T1 gear and the warriors won't be destroying rogues for T3 purchases until equilibrium is established?
Or are you extending this to "warriors get complete sets, period"?
Not that I have anything meaningful to contribute, simply curious about the scale and details of your question.
Everybody is your brother until the rent comes due.
Four warriors in 4/9 dreadnaught is when I'd stop defaulting pieces to warriors, beyond that its pretty much overkill even for four horsemen (I guess this depends on the strat you use) and it will make your life easier in many other fights as well. I think after that point your raid will gain more from rogues in BS than more tanks in DN.
