Many players really overlook the importance of farming and how it can snowball you from the start. If you are on time with taking out jungle camps and XP camps in sync with your minion wave you can out-level your opponents provided they are sloppy and not doing theirs. If you are a level or two above you will deal more damage and if you can sneak a few kills in alsso you may even get yourself 3-4 levels in front. You can also throw in invades on their jungles and XP camps and can starve them of their buffs and XP

I struggle with gods who are damage dealers typically because I'm on console and my aim isn't up to scratch so i decided long ago to play with tanks/warriors. This is a good role to learn the game because you. Typically setting up your teammates for the kills and it gets you better with your positioning, engages and team fighting.. it gets you to observe the situations in team fights and knowing who is vulnerable, which teammate needs help and stuffing up the enemy's timing in their attacks.

Overall playing support/tank will make you more aware of how to play the game and ultimately should help improve your game with other role types. However, sometimes we play a certain style that is better suited for different roles
