Will Of The Earth: stealth revamp?

Anyone know when the Will Of The Earth (25-29) blueside story arc got its most recent revamp? Been running some "completionist brackets" (doing all content, including legacy one offs) and just completed this revamped arc. It actually plays quite well now, offering a few surprising challenges via newer game mechanics.

*potential spoilers belwo*

It doesn't use any of GR's more sophisticated compound mission mechanics or instance map talk to contacts. But it does have a new custom ally, destructable objects that seem to start spawning baddies when they reach 50% (as if they turn into a Rikti or CoT portal) and then spawn more after that at regular intervals, and the mission chapters are clearly defined and titled blue.

I had played this once through a few years back after they added the completely non functional (but highly lucrative in terms of influence, prestige and xp) "spawning chamber" eggs on three legs. But that new destructable object model was the only prior revamp to the arc I had been aware of.

Regardless, thanks for going back at some point devs and polishing this one a little bit. If there is ever time in a development cycle, would LOVE to see a similar refreshing of the Terra Conspiracy arc (35-39 IIRC). Have always like that story most of all the DE legacy arcs though it plays terribly. Meanwhile, the Will Of The Earth story never really stood out to me. This little revamp has made it much more enjoyable and memorable. The revised mission mechanics really play well into the arc's narrative now.

Edit: Also, any defeat alls in the arc seem to have been migrated to much smaller more forgiving maps. And even the devouring at this level never seem to spawn swarms anymore. These two changes really alleviate the tedium that used to be inherent in all legacy DE content. Again, great job devs! *thumbs up*

The wiki article on the actual Will of the Earth pet is dated 2007.

Wow. Was this updated that long ago? Guess I've just been good at avoiding legacy content in this level bracket.

Yeah, I wouldn't be able to date it without referring to something like Paragon Wiki, but I knew it was old.
