I start running AK after I got my Ifrit weapon and ~1200 tomestone worth of DL, I don't think gears are that important for WHM in AK, but I don't want to be the under-geared one...
And after I got 2-3 piece AK gears to replace the AF, I start farming Garuda.
Now I'm just trying to get my 2nd quicktongue III and full DL to do Titan.
