I currently have the white bear at 6 stars, and my runes are all level 9 or 10. I was contemplating buying the dragon as a mount, which should provide an additional 20 M power. If I spend the same amount of money on runes, that would be about 5 M power. I am aware that power doesn't necessarily equate to strength (as it is, I am competitive with players 15-20 M stronger than I), but it costs a huge amount of coins to upgrade a lv. 10 rune, for what I see as very little tangible benefit. What do you people think?
