I feel as though a skeleton with a sniper spawning close by is a little pointless and somewhat negates the real terror that they should cause (aside from the damage of course).
I feel that skeletons with the 'eye of reach' should spawn further away from the player and not try to advance very much on the player either. This would result in being attacked unexpectedly from a higher point or some trees which could make for some intense moment and spice up exploration a little too.
They would have to be rare, perhaps their accuracy toned down a little and a few other tweaks that stop them from spawning at times when there are many skeletons.
Of course, these should not spawn far away during voyages when there are many skeletons to keep it balanced. They should spawn more like sentries on islands, spawn in and surprise you from afar and perhaps when you get close a few more could spawn to accompany him.
I really feel that this would be a fun and valuable - yet simple - change to the game.
Thank you for taking the time to read this, what do you think?
