In 1.6 you had
The USP which would be super accurate when standing still but had 12 bullets and you had to make them count
Then you had the glock which wasn't that strong but had a lot of tagging when combined with other glocks so it made rushes more effective
The AK was the OSOK weapon that was great at all ranges and wasn't OP because of the CT sided meta
The Colt was silence-able and was great at short to midrange distances
The AWP was the sniper rifle of choice with low fire rate but a OSOK to the body
The Deagle was the OSOK pistol
Why am I bringing all this up?
Because In CS Go
The P250 is the best eco weapon by far. Both teams can afford it and it's $300 for a OSOK. Compare that to 1.6 when you needed a deagle+sec ammo which would be around $800-1000. Suddenly, save rounds become almost obsolete unless you want to save 300 for an extra nade next round but for the most part you buy a p250 if you are saving
Because the deagle isn't the only OSOK pistol the P250, Tec-9, Five-Seven, and (used to be) CZ-75 become more viable than the deagle. Yes this adds "variety" but a 300$ OSOK weapon is not balanced.
The glock is also way too strong compared to how it used to be. This along with the peekers advantage is why CSGO is a much more CT sided game than 1.6.
The Deagle in CS GO is perfectly balanced but the weapons around it aren't.

Another thing that 1.6 triumphs over CS GO in is hitboxes. Jumping hitboxes are too accurate and standing still while shooting is too unreliable. Think this is me being a n00b crying or some other bullshit? Try and look at this video where the hitboxes get fucked up while someone on the enemy team is planting the bomb.
This is recorded on a LAN GAME with the best possible situation (aka online it's worse)

In conclusion, randomness should be as MINIMAL as possible in an esport and If a fan can balance the pistols better, then I think valve can.
Even if people overblow the concept of luck, it shouldn't be in an esport. Plain and simple. There is no reason valve adds standing inaccuracies to CS GO. (I know this existed in 1.6 but it was to a much lesser extent and it shouldn't have been in that game either.) I know it's not realistic but a game where you can run around with an M249 Machine Gun firing accurate shots at a low fire rate as well as a player getting shot in the body managing to be completely normal afterwards is a good sign that CS GO isn't realistic.
