Why is the game like this?

Idk how else to word the title so i'll just use an example:

Being stealthy just feels impossible even on easy

i know the easiest answer is that i'm just bad but on my third playtrough i still sometimes just get noticed bc the game decided so. Netrunning is literaly just putting a giant neon sign with gps over you head somehow telling everyone on the map your excact location. I used a supposedly untracable quickhack to make a guy fold in half while i was in cover. Literaly every other guy around him started shooting at the wall i was behind immediatly (about 100 meters away from them). The funniest thing to me is that after i started the quest that required to not get in combat it just marked it as failed immediatly even tough i never got into combat during the quest. I realy love this game but there are way too many times when it just feels like the creators wanted the players to not enjoy it, mechanics that sound good on paper but don't work in reality
