During the previous Live Letter, they basically said that these trials would be below Savage level:

In Unreal Trials, not only are primals scaled up to level 80, but they are also re-balanced accordingly. If we were to keep introducing new Unreal Trials, we’d have to spend a tremendous amount of cost to re-balance every trial all over again when the level cap is increased in the future. As such, our solution was to change the featured primal with each patch.

Some members of the development team felt that Titan deserved to be the first Unreal Trial, but Titan’s difficulty on release was around that of current Savage fights, which we felt was too difficult for the first Unreal Trial. Instead we decided on Shiva, as she had recently made a sort of appearance in Eden’s Verse.
