Trust - Enmity Agression Threshold

So I not 100% sure if this has come up before, and I complete understand if it has, but I was wondering: Can there be an adjustment to the Enmity% Threshold of which a Trust can be summoned? E.I. You are in a Colonization Reive and start hitting on the Root, Rock, Wall, etc... and become aggro'ed by the extreme unforgiving respawn of the Mobs at that reive. One of your Trusts dies in the process, but because you've attacked the root, which can't fight back or move, you can no longer resummon a trust to further assist you without dying or fleeing from the reive. Adjusting things like this would help if the event ever happened where we can summon them in Campaign, or become 'less hated' by a larger field mob like the Wildskeeper Reives.

On a Completely Random note: Why does Sakura have so much MP, if she doesn't cast or do anything?

She give geo regen though not sure why the mp pool.

She's technically considered a geomancer for character reference purposes by the game in order to give that effect, would be my guess. Therefore, geomancers have MP.
