Just did my first Shaper in metamorph league, they quadrupled his life (to something like 75 million I think) so I was interested to see how the fight would go. The phases were slightly longer but my current character does very decent DPS so it wasn't problematic.
Everything he drops now has value, as the fight is rare to get to with the new atlas. He did drop these boots,
which I promptly annuled hoping to hit a suffix,
which I did so I could put a second life mod on it. Cool.
