OK, yes, I know: The traditional take is that anything at a prior level cap gives less XP than anything among the "leveling" content of that same expansion. Yadayada "not intended to be leveling content," I've seen the community takes.
But, really... as a solo venture that has a "non-guaranteed" entry gear level required to access it, there's no reason in this 6.0+ world where XP is carefully controlled by having trash reward zero XP, for this solo venture that is the trust system not to be an exception.
You have this glorious self contained ecosystem as of level 71 where someone can just play this content on their own time in their own way, and there is no good reason for the trusts themselves to get over two times the XP of the player. Buff that player XP, even if it's just for trust runs, I beg you!
I just ran Matoya's relict on an 80 job both to bump Y'shtola less than a million XP to 90 (all 80 dungeons reward trusts 2mil and change) and to test the hope that maybe there could be some fun, XP-viable variety in the 80-81 trust game, and sadly, no, it's not a viable use of time for *my* XP bar. I say this as someone more than willing to live in trust dungeons for all my time in the game once unlocked, and accept the pace from 71-80 and 81-90. It's the best fun I've had in an MMO in over a decade, and there's no reason to break it up and slow it down so much from 80-81 (and presumably from 90-91, and so in in future expansions).
This is new territory, Endwalker is the first expansion with a "prior level cap" supported by trusts, and while 5 runs of mount gulg to go from 80-81 is only half the speed of much of the rest of the levels running trusts at the most current dungeon between 71 and 90, there's no reason for level 80 to go that slow.
Please, Squeenix, if you happen to see this thread, please let 80-81 in level 80 trust dungeons actually be something viable! There's room for these dungeons to be something more than just another option in the roulette with other expansions' "nope" dungeons!
Thank you for reading!
