You seem to read between the lines way to much.
Hallucination set is also insanely bad advice. Nightmare is already 100% tested and proven to big igniter sorc best relic set by a mile.
First of all, i never said it triumps nightmare. From a ceiling perspective, yeah nightmare is better. From a consistancy perspective, hallucination is much better (specially when you lack crit synergy, which is not that hard). Also, since you know about KR so much, just for you knowledge, Hallucination is slowly picking up pace and people are starting to switch from nightmare.
So for 1 you are assuming you always have a support there which is wrong straight away
Support buffs last 15 secs, if you cant move in the support buff for that much duration, there is simply something wrong with your gameplay.
Will also say im not lacking recourses to test things outside of target dummies which again these people test at which provide fake results.
I have been doing the highest content of lost ark on a week to week basis. In 80-90% situations i dont miss double doomsday. Also, you simply do not understand the important of spec on a spec class like sorc. Its a massive difference. Again, since you like KR so much, none of them run swiftness over spec on ring even without lvl 10 gems.
Here you go from google because English is not many peoples first language.
Consistent: acting or done in the same way over time, especially so as to be fair or accurate.
Here you preach about consistancy but then say hallucination is insanely bad advice. Either you dont know how hallucination works and how it is better over nightmare for certain things or you are plain ignorant.
Showing off ilvl doesnt mean jack shit about how good you are at the game or understand stuff about the game. I myself have a 1490 sorc. My knowledge about sorc isnt defined by my ilvl, nor do i need to show it to make my point.
