I press one key and my mage casts one frost bolt. A multiboxer can press one key and several mages can cast several frost bolts. That’s the difference. How about blizzard allows me to buy clones of my character that will repeat every one of my actions? That would certainly be a significant advantage in pve game play and over players that didn’t buy clones. How is that not pay to win? It’s similar to what many multiboxers do most of the time when they create 5 mages or 5 hunters etc. Multiboxing is a slightly better pay to win exploit since they can sometimes have the characters do different actions, though mostly they just clone and repeat the same actions across all the alts.
