Game Mechanics: NPC spells on PC in pvp(PETS)

[Critical]

I do recall Earth pets being less than extraordinary in PVP, that's why people used Air/Epic pet towards Kunark/Velious.

5/10 with an Earth pet is not unheard of, but the Sonic Bat and charming other NPC pets is a very viable strategy. Those NPCS have a different resist check, and Sonicbatstun is nearly unresistable even while not charmed in PVE. Thus the reason for charming mobs and having them parked at zone in.
