too much unfairness in this game

In addition to player strength, internet speed, mouse, keyboard, and monitor speeds also play a role. Even when using a mouse, there's a nearly two-second delay when turning around, and a bug that causes the player to suddenly move forward, making it feel extremely unfair.

A mouse has little fine control, making it nearly impossible to aim at medium or longer distances, but simply improving the quality makes it possible to kill with a single magazine at any distance.

A slow monitor speed makes it almost impossible to win at close range. If the enemy moves quickly, they'll teleport away, making it impossible to tell where they are.

The difference between pad and keyboard/mouse has not improved at all.
It's impossible for players of the same level to beat a gamepad at close range, and even with a level difference, a gamepad has the advantage.

Character control? That's a technique only advanced players can use, and it's impossible for the average player. A clear sense of unfairness remains.

Furthermore, most techniques can be used with a gamepad; keyboard and mouse offer no advantage.

Hiding the opponent's level is also questionable. There's an option for smurf players in the reporting section, but how do I identify them? No information is displayed on screen.

The design that makes it difficult to report players has still not been fixed.

What's the fun in intentionally making it difficult for players to report you?

In any case, the unfairness of player level needs to be fixed in all modes.

People who want to play against stronger opponents or opponents of their same level should be able to adjust their options accordingly.
