So let's compare it to the other weapons in the game.
SMGs. It outclasses every SMG in the game in all categories except for ammo capacity Which the P90 beats but is no longer being used.
ARs. Less damage, but significantly higher fire rate, with similar range means faster kill time for MP5 which can kill someone in less than a second even without headshots.
Shotguns. Shotguns will outdamage it at close range, but in all other scenarios it gets outclassed.
Sniper Rifles/DMRs. The MP5 will do what all snipers do and so much more. The only time a sniper is a better choice of weapon is when it comes to extreme distances, which with the current movement speed is negligible.
Summary. The MP5 has no downsides except for the fact that it can eat through ammo extremely quickly. It has faster kill times than ARs while maintaining an AR ammo capacity and a snipers range. Couple the high fire rate with little to no recoil or aim spread, and gameplay with the weapon is the same that can be accomplished on the desk top. Point and click, wait for the person to die. Repeat until all are dead.

The same can be said about any weapon, however, this is not CSGO or R6 Siege where the gun has recoil, aim spread, or some other mechanic that must be mastered for the gun to be good. The weapon has negligible recoil and aim spread, so you are not punished for spraying and praying. If you give someone who first joins the server an MP5, they will be able to use it with no issues what so ever, unlike other weapons on the server which can punish you for misusing them.
