Well you can, but the size of the runs are too small to do colossus and sometimes large enough to do cult. Though they whittle down to 4-1 players by the time you get to the hideout .
As for this:
They could easily make in realm lost halls more appealing if they just had the dungeon despawn timer be 10ish minutes, then have it go through a “reset” cycle, despawning, then quickly spawning another portal and repeating that cycle 5 times. giving you ideally 50 minutes to enter the realm and attempt a run, which gives room to plan and do multiple runs in a single realm. And while I would suggest persistence on the level of WoW dungeon portals, I already know the outcome of that (if you don’t, that would make it possible to enter the run at anytime, and because of how realm works imo would break Lost halls and would make the dungeon a joke.
I care mostly about the F2P community, seeing as I fucking hated the fact that pet yard upgrades were (and still are) bullshit, and they only give you one vault (should be 2 or 3 now but whatever), and I had to shell 20$ to bypass that grind wall. It’s completely unfair and downright abusive, so I wouldn’t care that much if they cut the fame costs by 75% so F2P players could have a better chance at running end game content (which requires a very good legendary and divine pet, and anyone saying otherwise is wrong).
