All These Robots

I hate complaining because I love this game. Like a lot. I just want to know what's up with all the robots now in PvP?? Every game I play now, unless I am in a full party, has at least one to two robots in the game now. You can tell they are robots because they carry ghost and heal as their spells, they never answer to anybody in game, and their death number in game is very high. It's ruining my gaming experience and pushing me to the point I'm not that interested in playing anymore. It's frustrating trying to play and have fun when you have robots that don't contribute or help at all on your team.
