Necro highest con solo-able

[Heated324]

I was just wondering what con is reliably solo-able for a necro. I'm currently level 25 and can solo yellows ~95% of the time with FM. There's never much issue really unless I hit a big wave of resists on fear (3-5).

Is this going to be sustainable? Or will I find this level of mob to be impossible to solo soon? Just wondering because I played a ranger on live and was lucky to be able to solo a dark blue that wasn't an animal (hah!) so was quite surprised when I found recently that I was able to kill yellows.
