I want an NPC to spar with of all types and varieties like Tank, Sorcerer, healer, DPS of any type and also the Summoner. And when I say varieties I mean different varieties like Trolls, Werebats, atronach, and more.
Sparring with NPC's will make it nice if we have a battle system to use such as a mode setting. And yes Sparring NPC's Assistants have three different modes you can train in Normal mode, Hard mode, and Difficult mode.
Sparring with an NPC is something good to add on for NPC Assistants & Homestead.

Bring it on you PVE & PVP milk drinkers, let's hear some noise for the Arena Forums(Good or Bad).
