I am hoping what with the different bows you can make that the higher the draw weight equals greater distance and power but actually animation wise take longer to draw.
Also another balancing mechanic could be holding your bow drawn before Takkar can't hold it anymore. So the more powerful bows take longer to draw and you can only "load" them for so long before having to fire or cancel the arrow, where as lighter bows can fire faster with quicker draws at the cost of distance and damage.
Thoughts ???
This is also the bonus for using other projectile weapons like the spear and sling, you can hold a spear loaded to cast for as long as you like and a sling can keep twirling above you head until your ready to cast (I sling IRL so I know, and throw Dark Age spears).
