I've always used warcry... guess I should take a look at the numbers. Normally I'm good at math, but when I try to do ffxi math I always seem to screw it up. Oh well, here goes.
At level 75 warcry raised attack just shy of 9% for the entire party, and lasts 30 seconds. Assuming the tank damage output sucks and the healer isn't trying to do any damage, you're buffing four people.
So four people get a roughly 4% damage buff for 30 seconds. The two merits reduce the recast timer by 20 seconds, which is a 20/(5*60) bonus to the damage. That's about 7% more damage.
Putting it all together:
Warcry, no merits: 4% damage buff for 30 sec/5 minutes
Warcry, no merits: 0.04*30/(5*60)
Warcry, no merits: 0.4% damage over time buff
Warcry, with two merits: 4% damage buff for 30 sec/4:40
Warcry, with two merits: 0.04*30/(4*60+40)
Warcry, with two merits: 0.43% damage over time buff
omg, did I do that right? That actually makes me sad, no joke. Please tell me I did that wrong. I want to be wrong about this.
The other things I guess I could do are 4/3/3 or 5/2/2 with one just left over (because I would rather hang myself from a @#%^ing tree than not have Berserk and Aggressor on the same timer).
5/2/2: Let's see, adding 1% DA, when I already have so much from merits and gear, will be pretty weak. I have Pole Grip, Brutal, and 4 merits already, so that's 21% right there. 1% more DA will increase damage by (100-21-1)/100 = 0.78%
4/3/3: So, if adding 10 more seconds of Bergressor nets me more than 0.78% damage over time increase than adding a 22nd point of Double Attack then 4/3/3 will surpass 5/2/2. Worst case senario for this build, acc capped: aggressor becomes worthless, and berserk is all I get. Basically, is 10 seconds of berserk worth more or less than the 22nd point of Double Attack.
So, 25% attack is going to be about 12% damage boost, and the merit will reduce the cooldown by 10 seconds.
Curiously, the damage boost of berserk drops out of the equation when you compare merit levels. Let the damage boost from Berserk = b. Then let 1+b = B. In this if Berserk gave a 20% boost then B would be 120%.
4:30 damage output: [(B * 180 seconds) + (100% * 90 seconds)]/270 seconds
4:40 damage output: [(B * 180 seconds) + (100% * 100 seconds)]/280 seconds
Starting with the 4:30 equation:
(180B seconds + 90 seconds)/270 seconds
(180B + 90)/270
(2B + 1)/3
Now, the 4:40 equation:
(180B seconds + 100 seconds)/280 seconds
(180B + 100)/280
(9B + 5)/14
Now, to compare them, you put them together as a ratio
When b (not B) is 12%, as in Berserk boosts your damage by 12%, then the damage increase over time is 3.28%. 4 DA + 3 Berserk > 5 DA + 2 Berserk
So 4/3/3 is the way to go.
Did I do that right?
