Poison DPS too low on my SRS.

Pob: https://pobb.in/RoGANSUL-JXj

I'm looking at other people POBS and I see pretty similar pobs with 20-30m dps on poison, some of them are a better but far from x2 or x3 my damage, I've added better clusters, +2 on helmet and some extra jewels on my pob and the total difference was between 30-40% at best.

I've configured manually the AG and spectres (Pale Seraphim + Arena Master), am I missing something else for the configuration part? Are there any mistakes with the build?

Also, I've read on this sub plenty of times that you need at least 18 dps to skip laser phase on uber lycia, I always skip it and this is bugging me because either 1. the 18m statement is false 2. Im not properly configuring the pob.

​

Would really appreciate a double check on the build. Also, I have 70 divs and this will probably be the last build I play this league as I'm really enjoying it so I can dump currency to fix/improve anything. Currently crafting +2 helmet, boots and better rings, will go with the jewels later.
