The bug(or miss setting) of Guecha Warrier's line of sight

Guecha has a LOS(line of sight) of 4. On the other hand, Feudal archer has a LOS of 6.
There is only a 1-point difference in their ranges.
Because of this, Guecha is extremely difficult to use.
If this isn’t a bug or a design flaw, then what is it?
