Projectile disapear when they reach a certain distance but they are still active.

In pvp a pretty popular spark build can flood an entire 1vs1 arena and even half of sarn arena with enought projectile speed and skill duration. Those projectile become invisible at some point but they still hit you wich make me reconsider the idea of this "active radius" concept.
