TO INT OR NOT TO INT
That is the question.
Throughout this guide, we recommend inting with purpose in order to achieve an advantageous game state. It's worth noting that, against a good team, small mistakes and miscalculations will be punished. Eventually, you may reach a point where the enemy team is too far ahead in items or levels for you to make progress against them. This is the risk of over-inting.
If you are an ARAM newcomer, then it's better over-int than under-int. Understand that there is a risk, take the risk anyway, and then evaluate whether the risk was worth it. Over time, you will refine your game sense and be able to make better decisions in the moment.
If you are an ARAM veteran, then it's better to under-int than over-int. Recognize when the enemy team takes too large of a risk, then knock them off-balance and keep them off-balance by pushing aggressively and relentlessly. Note that this does not mean that you should completely avoid inting. Instead, pick your moments carefully and execute them with precision.
Now, let's explore the most common situations in which you may choose to int with purpose.
