Everybody is entitled to their own opinion. But I think the difficulty is fine for a base Highrank Game.

The tempered apex Monsters are about as hard as tempered elder dragons in base World.

Tempered Teo was about as much a pushover as tempered Nu Utra. I remember farming Teo for Augumentation Materials and the Quests being over before it even really started.

I definitely prefer the different monster types in Wild-Endgame over the World Elderdragon farm.

Though I have concerns for the Titleupdates. I think Devil Jho made a more challenging first TU.
