Yes, this has now become a thing and it's indicative of a problem with how the Bozjan Fate Chain system is currently, not working very well, at all.

The current best way to get the Fate to spawn is get in a fresh instance and gun it straight to the spawn and begin killing Scorpions.

Now this is a known thing....certain less than savory individuals that know people are currently trying to hunt out fresh instances knowing full well that once FaF gets trapped behind another Fate it will go right to the back of the fate chain (which will take upwards of 2 hours to clear it, just for a shot at the S&F and duel for the drop) they go straight in with flarestar, they gun to Zone 3 and immediately kill all the MK1 Magitek mobs, that die fast and will force Mechanical Man to jump to the front of the queue.

I called out someone for doing this after spending a good 30 minutes with others exclusively killing Scorpions in a fresh instance, their reply

"Cry me a river"

They knew full well they were locking out the spawn for 2 hours, this wasn't some innocent "oh I'm new here" mistake, this was a very purposeful move to waste the time of other players that are frankly already sick of how dumb this whole fate system currently is in regards to the FaF fate chain.

But here's the thing, I may have voiced my distaste at that player, there are more doing the same, purposely trolling "because they can"

I don't blame them, I blame you SE, I blame you for not addressing the system when it was clear it was going to be a problem and it was going to be open to such abuse.

Simple answer, Decouple FaF/S&F from the other fates, I don't care if you give it a full instance cool down, let it spawn in the beginning, let it spawn in the end so people know if it's worth hanging around or moving instance and remove the ability for those that are blocking others from doing it because they think it's "Funny" to waste peoples' time.
