Ykesha v. Base Dmg

[Feanol]

I'm currently playing a Ranger in possession of two Ykesha weapons at 8 damage and 9 damage respectively. They both have a fast attack speed, 23/24. I'm dual wielding them.

My question is this: Am I going to realize a higher overall damage output by using slower weapons with higher base damage, such as 11 and 12 at say 25/27 delay but without the Ykesha proc effect?

Common sense tells me that even though my actual damage ratios will increase with the bigger badder weapons, the loss of Ykesha procs will lower my damage in a fight overall.

I've learned not to trust common sense when it comes to Sony's game mechanics though so I'm asking for help from someone who's done a bit more math and field testing than myself.
