The problem with destiny tiles is that we are avoiding it because of what it might be, not what it is. We don't know what it is. But if you have 2 moves left and a destiny tile in front of the boss, you can't afford to risk it being a -3 instead of a +1 or whatever. Maybe after a change the outcome of the destiny is likely different than the one it was just changed from, but that makes no difference when the risk, or the possibility, is what we have to avoid in the first place. We should not have to pay 5 gems to be faced with the exact same problem as we were faced with before spending the 5 gems.
