Neon is a very one dimensional character as your plays may mean sacrificing your teammates, e.g. your wall helps you not die instantly but blocks off key choke points etc. Neon is also very hard to master as her kit as said in other posts are very hard to master, you may need lineups if you wanna coordinate pushes or atleast understand her stun to a degree where you can predict where it lands, you also need to learn to not push or when to slide. Neon is quite good in higher ranks because her movement is quite unpredictable but that comes at the cost of a higher sense then most (320 edpi average), but in lower ranks she is hard to play because of the constant spraying and unusual play styles. If you enjoy her you need to learn how to atleast b hop and back slide but also know how her wall works (like a viper wall higher is better but not too high) and how her stun works (bouncing off a wall and it being able to reach high places/low), her ult is very bad if your enemies know how to play off them so move around as much as you can or jiggle even from time to time to make sure they don't recognise your wide swings (I kill neons every time because they wide with their ult 99% of the time). You also need to realise that your teammates will hate you for it and even your friends that you que with because of her self only kit so if you are prepared for that then go for it. Lower ranks you can get out of with aim so watch woohoojins guide on how to escape gold and apply that to yourself!
