Reduce Energy Costs for Act 4
Act 4 energy costs are so high for the amount of rewards in the current meta. It takes almost twice as much energy to fully explore Act 4 as it does to fully explore Act 5. There are so many paths and the paths are so long.
Humble suggestion: reduce the energy costs of moving one space in Act 4 from 3 energy to 2 energy. It would still cost a lot more energy to get through Act 4 than it would to get through Act 3, but the total cost of exploring Act 4 would be closer to the cost of Act 5 which I think makes more sense. New players to the game trying to clear content are going to get to Act 4 see how massive it is and many will just skip it because the rewards have not scaled with the growth of the meta. But then they'd be missing out on those 4 mastery points. Difficulty is good but it's just too energy intensive. Given the growth of the game it's reasonable to reduce the energy costs.
