Cricket chirping chamber

This is all I've been doing since I hit 45, with the exception of the Moonwater Arena soul shield.

I got the Darude Sandstorm outfit on my first run of that dungeon, I got the Pugilist outfit after 3 runs of that dungeon, I got the Inferno Lord's outfit on my first run of the Tomb of Exiles, I got the Blackram Narrow's outfit after a few runs of that dungeon, I eventually got Stinger after soloing Pinchy a bunch, and this morning I got the Red Mask after about 300 runs between my characters and the Ivory Scepter outfit. I still have a long way to go, especially for the Infinite Challenge one...

 My list so far

Rising Sun and Lunar Eclipse are the only ones in the current list that interest me, and they are only in the cash shop from what I can tell.

My god, does this game specifically weight boxes to not give you your classes weapon unless you use a brilliant key? I've used around 15 boxes per upgrade, with the high end being 47 Profane Jiangshi boxes. Currently sitting at 18 Siren boxes. Why did they have to give the game RNG, why can't devs just leave us alone and let us play the game?
