That will not spawn any more projectiles than using spawnProjectile itself. You are citing examples about how abusable this is, why not go bitch at Badspot about how abusable relays are? Or the Player kill event? If you want to bitch, first make sure your argument is at least close enough to solid ground that you can jump away if the ice cracks.
I wasn't exactly bitching about the addon, I was just stating a possible scenario.
I'm not saying relays aren't abusable, or that this add-on is bad. I'm merely saying that its significantly easier for those 30k+ id trolls that may not know how to quickly event something to that nature quickly
In my opinion the add-on is pretty good, it saves some event space.
