Lets be real, we're not going to get treasure hunter back until it's "fixed". Cause of the perceived increase in mythic/reaper boosted items. So, expect it to be back after the patch note: Treasure hunter boosts no longer increase the chance of mythic/reaper boosts.
Don't give SSG that much credit. It won't be in a patch note and they'll probably just randomly throw it on one weekend. Everyone will go crazy and test it and realize that it's not doing what it originally did.
I'm not attempting to disrespect SSG in any way, shape or form. I do think that altering the weekend bonus is for the worse. A lot of people like it and it incentives individuals to log on and participate in questing. It is one of the better, if not the best weekend bonus besides buddy bonus.
In a perfect world like someone mentioned, if they altered treasure hunter elixirs to do the same thing it would be even better (unfortunately because of the copying and pasting that has occurred it would make these treasure hunter elixirs too desired and they would be everywhere losing profits..)
