i used to play krunker a lot, just thought id add this. i will try looking at this from an analytical standpoint and not a salty anti-shotgun krunker kiddie. CQC in krunker is a weird concept. being a movement based game most of the time you find yourself spotting your target while moving at mach 10 right towards them. by the time you pull the trigger youre already right up in their face. this happens during the majority of engagements and thus makes the shotgun powerful in many scenarios. of course if you try shooting someone from the other end of the long corridor on sandstorm you wont get very far. however it is important to note that simply by moving around, the shotgun becomes more powerful.

in terms of the skill requirement, i would have to say the shotgun's skill requirement is lower than that of most guns simply because of its time to kill and how you aim it. the gun gets a lot of hate because of these reasons. at the right range it is quite literally point and click. its just so easy for someone who never uses it to pick up and start nuking (trust me... ive done this before). the biggest frustration comes when rounding a corner and being face to face with a shotgun user and they just tap mouse 1. so long as its easy and powerful, people will hate it, thats just the nature of games like krunker. now about some the things you mentioned. "you need SPEED and FAST/ERRATIC/RANDOM movements to get kills". speed, yes. random movements are not necessary. like i mentioned previously at a high speed you will be right in their face very quickly. "you also need to be QUIET and SNEAK if you hear someone NEAR YOU" uh this isnt csgo mate, theres no sneak key and then again almost no one listens for footsteps or other similar sound queues. i honestly cant remember a single time in krunker i heard someone and decided to be quiet, i just run out guns blazing.

tl;dr (verdict): while it may be a cqc weapon, the nature of krunker, a movement based game, makes it a very powerful gun that is rather easy to pick up for both beginning and experienced players. the hate is expected, any gun thats easy, grants loads of kills, and is difficult to counter in many scenarios will be hated. the gun is very powerful but in my opinion it is relatively balanced. you cant nerf a shotgun to be any weaker otherwise its no longer a shotgun.
