Why are you standing fishing in the middle of the spawn spot! ?
If you see that is too danger you should move to a safe area instead of standing there.
Weak pets should NOT be there.
Remember pets are your responsability.
I don't see a spawnkilling in your picture i just saw players trying to level up and you fishing in a dangerous area.
To all players if you are about to leave a map make sure that is safe for your pets to let them walk with you, if it's no safe, PLEASE, leave your pets in a safe area, in this case pu your pets near the castle where there's NO spawns spots.
If you are exploring, PLEASE, leave your pets in the pet storage. Use game store buyable pets instead of real money pets.
Before starting a PVP put your pets in a safe place to avoid loses remember when you are pvping you can accidently spawn monsters when you are running away, and if you have your pets with you the monsters can attack them and kill them.
One last thing do not blame the staff if you are not doing smart choices, your pets YOUR responsability.
