I could get a full army in 10-15 minutes. Without any energizers. Really.
I factor in the time it takes me to buy haste wands - 0 seconds, because I kept many on me at all times. That means it became a 30 second process to buff my wraiths whenever I wanted to.
I factor in the time it took me to buy hunting spears - 35 seconds, because I would keep 30 spears sitting in a given location that I would put there at the beginning of a reboot (which take place few and far between). That way, I could spend 3 minutes at the beginning of a reboot and then take 35 seconds to pick them all up with my wraiths.
I don't have a time stamped log, and I am not making another necromancer just to re-prove you wrong. When I did my 10-15 wraith runs I would hit teron and tlaxcala, using any access I had (tribunal NPCs or a control) for the first 3-4 NPCs, then I would just use wraiths to insta-kill things. Believe me. 10-15 minutes to be fully buffed with 20+ wraiths. Alone. If you can't do it, it isn't because it's impossible. I did it repeatedly -> and infact, I would get 15 wraiths and 20 wights in the same amount of time when I used the animate dead wand that I got wimped.
I can think of maybe 1? time I had another PC help me, and that was because he asked what I was doing

Anyone who plays a necromancer now is still the equivalent of 3-4 PCs of any other class. It's OBVIOUSLY an imbalanced class to anyone who plays a competitive pvp game.
Just a few tips incase you still are lost:
Keep rifts opened between tlax, teron, and the empire inn. That way, every tick you can sleep for huge mana gain. You can buy the haste wands beforehand. You can buy the spears beforehand. Take a look at my logs -> even when someone holy worded me they still died.
As far as 'how many that I spam-killed were good' -> I was walking through cities ALL DAY. Nobody even logged on to fight me after a short while. It was a joke. I only quit because the lighties actually surrendered, rofl. Benjamin was in shock at how they surrendered to me and not to him, even though he had been around for months. Necromancers are just far, far overpowered. If you can't see it you are a newbie.
