More class challenges thoughts

As I think we all agree on, class challenges are awesome, interesting, and useful. Their only problems are the serious difficulty issues, unlocking/recomendations, and how it's thrown economy for a loop.
As of now, unlocking the silver challenges seems kind of random. Also, some silver challenges, such as priest, require late game things, which really should not be needed for the class. I think that it would be better if ALL silver challenges were unlocked by some event. Whether it is at the start of your economic crash, or some other time is up to discussion. Also, no silver should require anything beyond full level class buildings, level 3 blacksmith, level 1 alchemist, or level 1-2 witch. Also, add all gods used to the recommended list.
Okay, on the subject of difficulty, I'm going to divide the challenges into three tiers: Too Hard or Too Easy. I will not comment on the non-updated golds.
Too Hard
Berserker Silver: This is one of the most edge cases of too hard, but it could stand to get a slight nerf because if enough Erosive Eelroots spawn you have to restart. I say just take them out of the mix, and maybe weaken the monsters/add a few more magic ones to the list.
Thief Silver: This challenge is currently one of the most brutal silvers out there. I think you should change the generation so the order of closeness is 9, 8, 7, 2, 3, 4, 5, and finally 6. Next, the monsters need a slight nerf, so it doesn't require you to find most of the boosters before you can fight your first monster. Finally, they need to nerf the bosses hp to somewhere between 300 and 500.
Rogue Silver: This is also a fringe case, but the boss could use a nerf or two on hp. Also, they should make Drac and the Pactmaker start near your position (10 tiles in any direction? Less?)
Priest Silver: This one isn't really too hard, it just shouldn't require you to have a can of Whupaz just to win (Although I managed to beat it without one). If they just nerf the boss, and change it to require something else (Maybe Witch 1, if they make the Zombie Corrosive and Weakening).
Sorcerer Silver: Now that you can no longer bring preps, Eeblis could use a nerf. Perhaps 444 or 500 hp? Also, the fact that you don't always get HALPMEH or PISORF make this challenge a bit random.
Fighter Gold: Ever since they fixed the Platemail bug, this level has become MUCH Harder. The boss needs an hp or damage nerf.
Rogue Gold: The problem here is the tendency for the game to throw you completely unwinnable situations. If they just made the "Islands bigger it would be fine.
Paladin Gold: This is nigh impossible. I say just make the boss a lot easier.
Bloodmage Gold: I haven't tried it, but most of the golds seem too hard
Wizard Gold: This is also a very scumming based level. Without the plate mail bug, you practically need a rock heart.
Too Easy
Wizard Silver: Between WEYTWUT and WONAFYT, the blink isn't challenging enough, and as long as you keep the boss in sight he's incredibly easy.
Any things not mentioned are fine or only need minor changes.
Last, challenges completely ruin the economic progression. I have a kingdom that has only beaten one dungeon (Vince's Vault), but has leveled up all 4 class buildings to max. I say gate bronze challenges to after robbed is completed, and make them only give a one time monetary bonus for their first completion.
