Here's my thoughts on the golds
Rogue Gold: Found it very simple, won first time. That being said CYDSTEPP was visible from spawn and 2 steps later I got Binlor. Then IMAWAL too. Found pactmaker later. Took Might and Knockback from Binlor then saved all my piety for Physical Resist boosts against the boss.
Warrior Gold: Wow this is hard. Best I've done is come within one shot of the boss. Every time a new batch of mobs spawns your run could be over. You get a Goo Blob? Over. Goblin? Over. I can't imagine trying to do it without the glitch Avatar discovered. I've been going Goblin, Conversion, Shield, reflex whupaz schaden. So close!

Wizard Gold: Wow, painful. I ran out of dark tiles about halfway through the level. Absolutely no clue how to handle this one.
