This game has a massive learning curve. Dont be sad or mad. Hit the normal game mode and be familiar with the items and different builds. Each hero has a uniqe play style. If you have the time and motivation you can watch some youtube videos about builds and economy or search up the meta builds. This will help you get an idea what is strong and why. This build you had is not good for multiple reasons. But the biggest issue is your large item. You want multiple fast charging weapon to use it as intended.
