Similarly, most players should find it reasonable easy to refarm some of their gear for "free" rerolls of curses.
Maybe this is where you're not seeing the big picture
Refarming gear in a reasonable timeframe may give you, like, 5 extra rerolls, especially if its gear from a quest you arent regularly running anyway (5 drops = 60 runs on average). If you're targeting a specific good curse, you may need 100 rerolls
on average to get it, which means if you're unlucky, you may need 200, 300, 500 rerolls
There's no way you can reasonably expect a player to farm the same item 500 times in order to get one curse in one slot
Even if you just broaden it to "a good curse", that's still maybe 1 in 10, generously, (so maybe 20-30-50 rerolls if you're unlucky) which again represents an unreasonable amount of regrinding for a single slot for a probably-mediocre benefit
When the cost >>> benefit, the system will be largely ignored, and that's just poor design - and thats what we're seeing people do with Decks right now
