I-L is believed to have higher LoS requirement than H-L (still have the ? mark in wikiwiki so dont fully believe in it yet)

if you failed the LoS check from I-L, you will go to H for a little lower LoS check (because K is not a fail-to-reach-requirement node, I-K seem to have its own branching rule)
