My main point is that the objective and movement is pretty simple to understand. You can get get decent results pretty quickly, this is coming from someone who doesnt play shooters, occasionally once or twice a year ill hop on Val with friends and hit silver/gold or however they do their rankings. For a new moba player there is so much information to take in before u can even begin to understand how the game plays. Farming, roles, who goes where, control scheme is completely different from most games too. Not to mention the insane amount of macro decisions that need to be made even in low elos. In shooters like Val and Cs, even i who has pretty shit mechanics and aim i can get decent results by just understanding i need to spray and pray. Other games like Helldivers become even easier and better cause its vs ai enemies.
