Let me copy/paste my last opinion on that topic, because i already have around 10 for how OP/broken and noob easy to use Mastiff is:
70 damage for a shotgun should be the optimal damage and its balanced towards the TTK and other weapon damage. With the shotgun you got a lot easier time to aim, because your crosshair is like 10x time bigger and the range of the shot is quite big.
Also 70 damage means you can 2 shot a enemy with EVO shield, and 3 shot an enemy with Purple armor, if all the shots are right on the target.
Its more than enough damage for a shotgun.
70 damage is like 65% of your total hp if you have purple armor(even more on LP), saying this isn`t enough is complete joke in my eyes.
I said what i think about the mastiff and for me its completely broken and OP, no CP weapon should do 120+ none headshot damage in a close range, should have that wide range of its spread, be that noob frendly and have that range to shoot from distance, yet being a ***** shotgun.
Completely noob friendly and unbalanced.
Continue like that Respawn and soon you will lose a lot of your playerbase, and the game will be filled with even more cheaters.
