A targeting system is the server-side layer that decides who you are engaging and what counts as a valid target. It is how abilities know who to stun, drains know who to lifesteal from, and the server knows when damage should apply, when assists should credit, and when you are considered in combat. Instead of everything being pure crosshair contact with no memory, the server tracks target state and uses it to make fights consistent.
The feel depends on how strict it is. With soft targeting, you still aim normally, but once you hit or mark someone, your next few skills reliably resolve on that player as long as they stay in range and line of sight. With lock-on or tab targeting, you actively select an enemy and spells snap to them, shifting skill from flick aim to spacing, timing cooldowns, breaking line of sight, and target swaps under pressure. You see this a lot in class PvP, arenas, and boss fights where mis-targeting in a crowd would make kits feel random.
It also shows up as rules, not just aiming help. Team modes use it to block friendly fire and prevent damage in spawn or safe zones. Hunt-style modes assign a target and track pursuit. Factions and raid servers often tie target engagement into combat tagging so you cannot /home, /spawn, or log out the moment you trade hits. When it is implemented well, fights are readable: you can tell who you are on, who is on you, and why the server allowed or denied an action.
