New Medic weapon looks awesome, but...

We're given info that the new medic weapon will upgradeable through tiers.



That sounds awesome! But, then we're told that the shotgun and assault rifle versions are on separate tiers.



That's not so awesome. I love the idea but the end goal should have a little variety.



Why do you not balance the shotgun and assault rifle variant to be equal in tier. This way I can choose which utility is needed. Close quarters maps with a shotgun or hallway/corridor shooting with an assault.
