I think they did change it to population cost now, yes. But it's still a lot more taxing than before. In the past, if something like the defenceless caravan quest turned up at one of your naval or DLU cities, you could build 6-8 slingers and deal with it. Now that sort of quest only works if you have OLU nukes, and only the right sort of nukes. In a way it is good, making you put more effort in. But some quests don't feel worth it. The +60% favour can be useful, yes. But so far as I know, we can't get the rare or epic favour production bonuses from quests, so no matter how much effort you have to put in to get the quest, you get the same reward. I know it's a reward that works on all cities, but it still doesn't seem as useful. If I choose that reward, it's because I want the wisdom coins, or its the easier option, and less because I want the reward. If you have a lot of cities with high temple levels, it may be better, I suppose, but it'd be nice to see the favour tokens scale as well in some way, given that every other token does so.
