I HAD an infiltrator...
After I made a new account I stopped playing only Infil so I could experience the rest of the game. My swordskill was one of the highest in Atamara and I stabbed Ottar, ruler of Tara. I HAD a boss infiltrator 
In my memmory it takes longer to built an 80/80 infiltrator than 2 months. That's without the having to get enough h/p to be even considered when you have to start over with a new knight.
