The problem with hopcount metric is easy to explain. Hopcount metric based 
routing tries to minimize the number of hops to the destination. This works 
well in wired networks, but with mesh networks it tries to use links 
connection stations far away. This links are typically lossy and unstable, so 
you don't get a working mesh.

You can try to reduce this problem with better hysteresis (filtering links 
with signalstrength & lossrate parameters), but this might split the net 
because you don't propagate the only link (it was "too bad") connecting two 
parts of a mesh cloud.
