I get what you’re saying, but the answers to your questions are already laid out in the Update post for 6.1. Your questions are just wishful thinking for right now, and in fact all of the answers, however unsatisfying you may find them, have already been stated.
Mythic, pet, and weapons in the new Forge levels are exclusives that need to be unlocked in the Soul Forge levels 11-20. They have announced Cursed Gnome Bait as forthcoming in the future for guaranteed Cursed Gnomes, but they haven’t shown up yet on any offers that have been posted here.
Maybe blowback about the rarity of Cursed Runes might change their mind about scarcity of drops, but I wouldn’t expect it anytime soon.
Now, if you are making these as suggestions to the devs to make future changes, then that’s a different thing, but I don’t think you’re going to get a response due to the reasons stated above.
