Lesson of S10 is missed opportunity and power is overwhelming. Chaos armor was a fantastic idea that was botched on execution. Players have palpatine type perk power with nowhere to use it. 
Botched → AT season end chaos armor is gone. ITs our best idea and we wasted it.
Many chaos armors still broken even after PTR reports.
No mythic version of chaos armor that is wild. Can go in any slot with joker pictures.
Why no chaos gob? Why u hate gobs?
No midseason content. WE lost this to have polished season. ITs not working yet. There is nothing to do with all this power. Bored players quit.
OMG HYPE!!! —> Chaos armor permanent addition. ( its ok it it has to lose 20% bonus, it can just be max). Season will be easier to farm chaos armor so play the season now! When it moves to eternal it will be more rare for the chaos sigils and other things related to season.
Chaos armors fixed from feedback on PTR.
Super chase mythic chaos versions earnable. These are wild and can go in any armor slot and always have 2 - 4 GA.
Chaos Goblin added.
Midseason content added back in. Players have new scaling content like Abottoir of Belial to push the limits and earn special cosmetics, mounts, new runes, new gems, and other exclusing content. Earnable at lowest level in area but high pushing is more rewards.
