Blood Legion has so far managed to get World First:
Protectors of the Endless
It's looking very promising for them to secure World First Sha of Fear. I say that because I think in the time that Terrace has been released, Blood Legion has been capable of killing all three with a very very short amount of time. So unless any EU guilds can kill it quicker when it releases then I see Blood Legion securing Tier 14. Disappointing to see that Terrace wasn't that big of a challenge overall.
Edit: This isn't a debate on if US is better than EU at all, both have equal chance to get World First due to who kills it faster after release. Just stating that Terrace itself looks very easy if it's been killed less than 24hrs of release
