This feels like one of the most reliable run’n’gun heroes so far:
Guaranteed instakill on specials, with 20% max ammo refund is pretty strong already, but the swiftbow allows for shooting without slowing down to aim, enabling the elf to kite warpfire and packmaster, or dodge ratling shots.
Extending the passive regeneration adds some nice sustain to the entire team, especially if there is a +15% HP warrior priest on the team.
It’s fun to play as but since there is so much ammo lying around I’m sure it feels oppressive for the rats.
Perhaps reduce ammo pickups to 50% max ammo instead of a full top up?
