Thanks for all the continued support with your theorycrafting, fierydemise.
The ranking of Assurance of Consequence is pretty surprising, but then again, like you mentioned, it is the highest ranking ICD trinket (not including agi_5). It feels like that would be the best choice for 'reliability', when coupled with Thoks Tail Tip on progression, depending of course on if they tweak RPPM mechanics any more in the near future.
Hopefully GC replies to that tweet and we get some clarification around the eligible classes for Thoks. I personally think its pretty ridiculous if we will be able to use it, but you never know..
I'm also assuming that the Sigil of Rampage 2/3 Target EP requires that you're able to cleave during the entirety of the encounter. Realistically in SoO this may only occur on Galakras, so it will rarely be worth such a high valuation.
