Ranger has more problems so finding out the correct stat to boost the rate of a very significant stat (with the addition of Dead Aim and Jishnu's) is still not very important?

Or: Problem A is bigger than problem B, so problem B is "not very important".

That's nice logic, I like it. Hey, curing cancer is more important than curbing third world famine and povety. Therefor curing third world famine and poverty is "not very important".

Increasing haste is more important than increasing Double Attack/Triple Attack. Therefor increasing Double and Triple Attack is not very important.

Atma plays a bigger role to your damage than weaponskill sets. Therefor having a weaponskill set is not very important.

Need me to go on?
