Ice King and Demon are both garbage, agreed. Your changes sound like they'd make them feasible. I like your fix for elemental ranger too, but does the stance have to increase AP cost too? I feel like they damage increase would have to be significant to outweigh the additional AP cost. If you have 9 AP and quickdraw, are 2 elemental attacks better than 3 normal attacks. Perhaps the math would say yes for certain enemies, but intuitively I see it being unlikely for most situations. But then, it could be kind of overpowered with 0 AP cost, as it would be a significant damage increase without any downside at all. It is at least kind of interesting now how you have to think your attacks through, but it's just not versatile enough to make up for the times it limits you.
Perhaps the stance could require a 1 AP activation and deactivation cost, but not increase attack costs? So you would still have to make a good decision of when to use it or you'd waste AP. Also, perhaps this stance could stack with the other stances?
A question about five-star diner: does it double the negative effects of a food item as well? If something gives you -1 speed normally, will it give -2 speed with five star diner? If so, that should change, because then it makes certain food items even less desirable. I do think five star diner would be a good talent if, like Thorsten said, healing potions weren't so common. Perhaps giving their heals a flat percentage would help make food more useful for hardier characters. Not sure what percentages would be best. 10% by default, 20% with the talent? Some foods would have different percents I imagine, but that ballpark range might be good.
