Opening a fight with jump>drakes "seems" to get significantly less hate than just opening with drakes
Assuming you're talking Spirit/Soul Jump here, this is very possible actually, considering that the first successful attack performed against a mob seems to get some sort of bonus to hate. For example, ever had scenarios where one person engages a mob with a low-damage hit, and then a second after someone else hits it for higher damage than the first guy? Going purely by the numbers, the 2nd guy should be stealing hate off the 1st guy, but typically that isn't what happens. The person who landed the lower-damage hit will usually still have hate immediately after that, unless the 2nd hit was leaps and bounds ahead of the 1st one. (I'm only talking about immediately after the 2nd person connects with his hit; whoever has hate 10+ seconds after that is all situational)
In other words, any sort of "bonus" hate gained by the first successful attack on a mob *might* be negated if the first attack is Spirit/Soul Jump, and if that's the case, a WS after that wouldn't be getting as much hate as it would if it were the first action.
