For the new hand cannon to be even viable, you have to be 400 power just to get a tier 3 weapon from Ada's Workbench.
This being said to get to that power it would probably take a month if your not actively on all day, which lead me to say THIS GAME IS WORSE THAN CONCORD
This event is only active for a WEEK then the weapons are gone.

Not sure if it is hand cannon in general, but it feels very weak.
