SEE Solos Fury-Class Interceptor Tier of Proving Grounds + ReTrying SLKR's Node in Ult. journey

I heard that SEE is capable of soloing the Fury-Class Interceptor tier of the Proving Grounds event, and turns out, the rumors are true! SEE is such a piece of crap but he brings a little worth here!

The other thing is I try to complete SLKR's tier of the Ultimate Journey Event using suggestions from my comments section, but it still just comes up short.

Someone, PLEASE give me the in -depth strategy insights to beat this tier! This is obnoxious and I'm sick of it!
