sageEliminates weapon variety: Its so good that all the other primaries are considered "trolling"
currently the same for every 6s weapon slot in the game except maybe soldier melees and secondaries
sageViewlock: While medigun lets you look around while healing, crossbow forces you to place your crosshair at your teammate and lose situational awareness, wich might stop you from seeing a soldier jumping you or some scout flanking for you.
and? seems fair to me that you cant give ur teammate 150 health across the map while also perfectly dodging everything coming at u. if u dont want to lose awareness u can literally not pull out the xbow
