So, this is the build I use when I feel braindead regarding mechanics and I want to try as little as possible.

The aim is to spam your Volley ALL. THE. TIME. from mid game onwards. That Volley will be an area attack, and with our build and passive, will slow everyone, deal damage to everyone, shred their armor, ignore their armor, deal both magic and physical damage. You will control the whole enemy team, deny lane advances, and be extremely annoying while mowing down their hp volley by volley from afar.

Your ulti will be on relatively low cooldown to prepare a lane kill, snipe someone across the map to help your teammates, or do a critical strike in a teamfight.

There's not much to think about, because there's very little you can do in terms of mechanics with this build. You are not focusing full AA, you want to use Volley, which you aim in the general direction of the enemy (but you may have to aim and time your volley so that an arrow will hit your enemy in a creep gap in lane). Although this is a braindead build in terms of mechanics, it does need strategical thinking as always.
