I would be inclined to say that your 12th house planets are not so challenging because they have easy flowing aspects, sextile and trine, out to other planets in the chart which can help give them more conscious expression. Like Mars to Jupiter and Saturn. And there is some favorable reception between them as well.
In my opinion, there are no hard charts. All charts have challenges and gifts and it is our job to live them to the best of our ability. We can all do that, no matter the chart.
