Now I haven't run numbers on this but I really feel a 50% energy cost reduction in backstab would solve our problems
It would make recharging dances much less painful but doesn't increase our DPS within dance, maybe 50% is a tad much but I think we can all agree that backstabs energy cost per yield is ridiculous
It would also probably be enough to close some of the gap towards assassination
It would also allow us to be slightly more aggressive with our dance uses knowing that we don't have to be quite as perfect with them
