So tell me what exactly is wrong in realism and rest, because it looks like you are only a troll who know nothing about physics...
My video links library is gold sometimes.
EDIT:
It's not a question about if it's realistic or not, it's about that noone would play this game if the realism part was
the prime target.
So realism is no argument that will help alot.
Fact is that this would only help big groups of archers which are powerful enough as the yare now.
Besides that its just silly to think about arrows weight affecting shields when we have horses riding into walls and
invisible barriers and stuff.
Would it make the game better? No. Would it be fine balance wise? No. Should we add it? No.
