"As of Update 11.3, Toxic Ancients are very hard to find due to the infested becoming purely an invasion faction, making Firestorm much harder to farm in game."

I don't know about 'very hard to find'. Infested invasions are fairly regular, and there's always ODD and ODS. You don't even need your own keys; there are constantly people hosting them in Recruiting.

I actually got a few Firestorm from pug ODDs.
