I don't say it's about ego in general, i was responding to the person based on their comment. "I'm pretty new to battlefield and to shooters" Every game get's time to learn, it's not only about being good at aiming and more about strategy and the way you play, go slow, check every corner with your weapon ADSed, move on maps while choosing paths with cover, not right in the open. This is the reason why most people die instantly, they run around like headless chickens and get beamed by a person that checks his surroundings. Once you'll know the map and know what to do you'll be able to move faster.
Just the same as people complaining about campers, is the issue them choosing a strategic point or people rushing in without checking, i think the latter. E-sports is considered a sport for a reason, it takes patience and time to learn. If someone's really passionate they will put all the time needed into it and eventually become good. Aiming is muscle memory, this takes time and there's no way around, if you're on pc watch video's on how to set your Nvidia or AMD settings optimized for gaming, here's a big one on pc, go to mouse settings and disable 'improve the precision of the pointer' this will improve your aim in a very noticeable way, tweak sensitivity till it has the perfect feel, put your mouse DPI no higher than 800.. Anyways, you get the point, gaming isn't just about jumping into a map and shooting your weapon around.
Many don't seem to understand this because many are influenced by streamers where their whole brand is based around "i got 100 kills" like a bunch of toddlers. People get obsessed about their rank on the scoreboard, they start to think they suck and move over to bot lobbies, maybe instead play the game and do not care about the amount of kills you get. Impatience, lack of understanding and brainwashing by streamers is the core of all these complaints and what makes people give up before they've even tried. You can not get good in three months, it takes years, it's a passion. So either people come play bots and don't complain, or they put in the work, it's that simple.
Play the game, have fun and don't give a F about score, you'll see you'll stop wanting to play bots because the feeling you win a gunfight against a real person compared to a bot is a hundred times more satisfying.
