You do know you can kill mobs to decide which CE you want to pop right? I dont have the sheet at hand but i believe for north sector you have to kill about 20 Scorpion Mechs, then it will queue the CE "Metal Fox Chaos" into the area.

Imagine it like this.

Bottom kills 20x Machine to pop CE > their their the first so it pops straight
You kill 20x Scorpion in North > Your CE will pop when the bottom one is finished

this way you can pretty much ensure that your fate pops once per hour, i found this out the hard way as i too was waiting 3h for the exact same one, cept i went to dr. google, learned and popped it and kept instance jumping till i had my drop 3h later.

Rants are fine just remember nothing in Bozja is random, every single CE has a mob trigger and YOU can decide which one spawns, ALL jobs can at least solo mobs, if not pull 3. If you pull 3 a time and considering they pop once a min you can yourself add Metal Fox Chaos and its pre fates "in absence of friends" and "Steel and Flame" to the queue in 10min.

Or you wait for 3h hoping someone else knows this.

This is also why ppl pull in mobs during fates (besides the cluster thing) it just helps to pop more CE.
