i got that from googleSo, by this definition, summoner literally shouldn't exist, since minions and sentries do all the fighting without needing any input, and whips, despite not being auto-aim, have pretty big range and cover a wide area, a.k.a you shouldn't have to aim them.
You're forgetting rhe fact that terraria is a game. Improving skill isn't the only thing you can do. If a person wants homing weapons to carry them through hard boss fights - let them do so. Maybe they enjoy building or exploring caves more that wasting days on a boss fight that they can't beat because they can't aim.
