Yeah, Ultimate is literally all recycled assets. If anything, Hidden Canals has a higher likelihood of delaying Eureka, and even then that's a stretch.
Also, I decided to look at bswpayton's thread creating history, and now I'm trying to decide whether or not he's trolling. A normal person does not make a thread advocating for people to kick DPS who don't AoE in dungeons AND a different thread about why SE doesn't allow parsing when they keep designing fights with enrages, and then turn around to complain about how the devs choose to spend development resources towards a specific portion of the community that's at the opposite end of the spectrum.
