What I've noticed in Gold Elo

This is just some observations I've made in my short time in gold elo, and please be aware I am fully guilty of the mistakes I am going to list, hence me being in such an elo. 90% of the games I've been have been lost by either team due to three main reasons:

Getting caught out - This one's huge. Especially in late game as a 4v5 makes things astronomically difficult.

Not respecting your enemy - Realistically you should never go beyond 3 deaths in lane. Even if theyre just one kill above you thats a lead that'll give them the edge in duels. Be passive when they're ahead and don't risk letting them snowball.

Teamfighting - Nearly every team fight I witness turns into a blind fiesta where people try to kill whoever's in front of them. And no, focusing the adc will not be the priority every single time. Remind yourself who's fed on their team, who's fed on yours (so you can peel for them), and how fed you are.

I don't know these are just some of the common mistakes in my elo, can you guys think of any other?
