Just because you don’t think you’re going to get picked doesn’t mean you shouldn’t scout. There are a lot of benefits to scouting now.
For one it gets you in the healthy habit now. It’s better to get into it and begin generating that culture now, since from what i’ve seen a healthy and proper scouting culture is developed overtime. And it’ll be easier to retain it rather than gunning for it later.
Secondly, as mentioned by others, you can use the information to help with qualifiers as well as elims. Even if it’s just your first event, as it goes on if you have the right information jotted down you can help your drive team by giving them information that might be crucial for winning a match that you might have otherwise lost. And who knows? That one match might have gotten you into a picking position.
Thirdly, it has also been mentioned that if you are picked scouting data is an appealing thing to have. Not only can it be something you’re chosen for specifically if you have a good way of displaying your data, it can also help your captain pick their second (or third) pick for your alliance.
Now since you are new to it, starting out slow isn’t necessarily a bad thing. And every team culture is different, and you just might need to find the best way for your team to scout and that might take time. So take it slow and find the best method for your team. It is definitely worth starting now.
