I'd like to know if the severe drop in escalation chests spawning is done on purpose.  Prior to the new content drop almost every chest that would spawn on a map were escalation caches.  Now you're LUCKY if there is even 1 cache per map clear.  With this nerfed spawn rate of caches is the limited rate at which escalation cache keys drop.  In my opinion the season of escalation isn't one of the more popular seasons and with this drastic nerf in drop rates of keys and caches I'm regretting running charaters in that season.  I'm really hoping this was an accident and it's in the plan to restore the spawn/drop rates.
