Rangers seem too strong. They can dance around enemies and fire from long distances while doing great amounts of damage. In that 6 minute video I don't think the player got hit once. Needs adjusting. Either the dammage they do needs to be way less, they need to have to stop moving to shoot, or the enemies need faster and more responsive projectiles.
Also PP recovers too easily. Make it so you need to actually conserve those special bullet strikes.
