FIXED. Read below.
Correct me if I have any math wrong, this is how I think the attacks per animation will compare between now and Update 5. No other bonus attacks are calculated in here and bonuses to attack speed is disregarded.
The purpose of these charts is to compare the DPS drop in rogues.
A rogue can have Improved and Greater TWF, but first some charts on how many attacks one would get upon completing an attack animation cycle.
Pre-Update 5
2 2 1 1 = Normal (6 attacks)
2 2 1 1 = TWF (6 attacks)
2 2 2 1 = ITWF (7 attacks)
2 2 2 2 = GTWF (8 attacks)
Post-Update 5
(1+.2) (1+.2) (1+.2) (1+.2) = Normal (4.8 attacks)
(1+.4) (1+.4) (1+.4) (1+.4) = TWF (5.6 attacks)
(1+.6) (1+.6) (1+.6) (1+.6) = ITWF (6.4 attacks)
(1+.8) (1+.8) (1+.8) (1+.8) = GTWF (7.2 attacks)
So after fixing the tables and re-doing the math, it seems as if the drop in DPS for pure rogues with GTWF is only 10%? I guess I can live with that, but in my honest opinion it has nothing to do with fixing lag.
