This an open world game...freedom to do what you want, play how you want is the premise
If I have developed enough of an Acrobatic skill to jump into unreachable areas, I have the full right to enjoy the rewards of focusing on acrobatics.
If that means mounting a rock and picking off my enemies, so be it...
Any enemy that wishes to catch me should go and work on their Acrobatics like I did
Edit..or like a previous poster said, the enemy should run out of range of my arrows and force me to come looking for them
