We did try to add some things that are useful at any level. Notably, the potions stack with everything (or they should do, please let us know if they don't). The final reward is repeatable and, so far as I know, unavailable anywhere else.
There will be a requirement for progressing further in the story line, so you'll need to complete the zone a few times. There are actually two secrets that I don't think anyone has discovered yet. One will be required for an element of the future content and the other will provide a very unique click as reward.
However, it's appreciated that regardless of all this, it's not the same as new tier appropriate content that will be a challenge for you with rewards that match the risk.
The plan is to both push this story arc into t8/9 and beyond, with content not directly related to this story also pushing beyond tier 9. No promises and no guarantees but my intent is to create two or three more group zones and three raid zones. Plus one special, new to THF event.
PS we completed Sol ro not that long ago and I've run cotw with my group of six and cotw is a big step up in difficulty; the Dominion trash hits about as hard as aviaks
