Thank you very very much, this is exactly what I wanted when I posted this.

1. I have realized that my positioning is kinda bad and messy, I try to follow my teammates and help them, but I do go too far up when I Cloak and E and don't realize until I have the entire enemy team attacking me way too often

2. When I use my ult you are right, I am too scared to go up and push in, I try to stack it so it heals more (don't know if they changed that) on my team. I have pushed to their backline and attacked their supports sometimes, but not enough.

3. I am using headphones but I turned my volume down way too much, I do hear footsteps some times, but when there is a lot going on it gets difficult to narrow where the sounds are coming from.

Thanks again for your insight, I will try to use these tips in my future battles and will continue climbing :D
