The amount of runs to level trust should be lower.

I guess I didn’t realize you could unlock leveling trusts before level 80...

What's your point?
You think I'm going to spend fifty hours leveling all the trusts... just because?

I'm currently doing the HW beast tribe stuff on a character in that level range because it's something I can do while waiting for queues to pop, get exp while doing it and as a side benefit this also unlocks more purchasable vendor items.
It says a lot when content from two expansions past is more rewarding than trusts.
