If my maths are correct, it’s impossible to reach Conquest max reward if you don’t buy Inquisitors

To my surprise I just got the max crate this morning. Getting all non-Inq feats and cleaning all nodes got me within 4 keycards of max crate. The most purges I could get on the Boss Node with JML and 4 Inqisitors (and voluntary vanguard) was 14 before I was down to the last Jedi. It turned out that using 5th Brother lead and full Inquisitor squad could get me 22 purges. I finally got the rng right to actually have them survive the battle and get the 4 keycards I needed. I was up to 265 purges. My last set of disks was Vitality x 2, Amplified Agony x2, Caustic Emissions, and Unstable Decelerator. Quite surprised it actually worked. One day to spare.
