TL:DR of below is when more content comes out in 8.2-8.3.5 will this raid be worth returning to? Especially when many are already choosing mythic BOD over this raid.
Thing is I have been playing this game long enough to know how things trend and how the population consumes the content. I also know how my personal joy from a two boss encounter goes down when compared to other content getting released.
As stated before will people play Crucible in 8.3.5? People were playing Trial of Valor mythic in 7.3.5 in healthy numbers because it had mogs people wanted that looked unique. It also brought AP which was usable. The gear became ireelevant at that point.
Also to tout the success of Trial of Valor a bit more it competed with Tomb of Sargaras and Argus the Burning Thronw that had tougher bosses and better gear by miles.
So my thoughts here come from that perspective because time is limited and people will only invest enough time to things they see as rewarding for their time invested. Most people would just join the most current content for the power level increases instead of bothering with old content. The only motivation people have in later points is the type of rewards they get.
Crucible, devoid of unique mog appearances and trinkets of interest for every class and spec, has lead many guilds to just put this raid as an after thought secondary to their progression through Mythic BoD.
So again ill ask, do you think people will revisit this raid in 8.3.5?
