I'm not fond of it. The zerging of mid seems to be Square obliging requests for a mode without objectives, without strategy or tactics. Basically deathmatch. I tried it as WHM the other day, and I could not see whether what I was doing contributed to our sucess at all. People died, they were raised and went back in the fray. It's not like Secure, where if someone dies, the enemy gains a clear advantage, and start working down other members of your team. A healer was needed and did make a difference. Here people run in, take damage, run back to the group, get healed, then run back in; rinse and repeat. The no reward in that. I tried sleeping some of the enemy team, but I don't know if that helped. Overall Slaughter has been unrewarding. I like Secure.
