maybe he meant disable all buffs from optics.
although the 33% aspd is nice on a SN aha
I don't think that's what he meant. Besides call spirit doesn't DRASTICALLY change an SN's gameplay (given that is the only buff on it). 
Yes that what i ment and call spirit + body reco changes the SN gameplay espeically when SN vs Knight [ Hit till your hp reaches 3k? then run and heal

]
You guys don't understand anything ...
Let's start with Megs/Bris/Sleps they are SQI but all classes can wear which makes a balance in its way .
But when it comes to mjol/SoM/VO they are made to complete and overcome weakness for the classes that can equip them for example SoM which have a magic improvement
but what will happen if the opponet has GTB ? that's why they can pierce Demi-human's defence and by forcing GTB instead of wearing toad they can easily overcome thier weakness .
Now let's talk about Vesper Optics, it gives reduction from all elements because GS can't wear Toad shield but SN can wear shields which kill that purpose . it gives 20% MHP since GS
have low hp but SN have heal which also kill its purpose , it's the best SQI in tanking .
I don't mind a SN using
ONE SQI since if they used SoM/Mjol/etc you get a great force but not that good defence and if they used VO only they get a great defence but not
a good force .
Using two means having Force and defence which makes it unbalanced .
I asked Aryia to clear Forest with her SN [ by using OV and mjol or SoM ? ] and guess what
it was cleared I will just resay what Dreus said to some people in-game asking for more buffs for OV :
" You're not suposed to kill champs with GS
Don't forget that GS have an access to Non trans PvP/WoE "Same thing goes to SN
