Shorten Hollow Halls for Solo Players

Shorten the dungeon of Holow Halls by 66% when entering it solo. It's a game killer and actually moved me uninstall the game. Moved solo through that whole slog, because I wasn't aware it was "optional content" as there's no hint to that whatsoever, it's just an "easy" quest like any other.
Got through it and at the end there's a teleporter that, when used teleports to the start for some hell's known reason without updating the quest or gaining anything out of that whole damnable ordeal. Exp is laughable, enemies are HP sponges and fighting off hordes as a mage is annoying to no end, the layout is boring, the mechanics are annoying and one gets really tired of them after the second time.
Apparently there's an NPC? Wouldn't know since I got teleported to the start without gaining anything at all.
100% miserable experience.
