Nitpick: why timer/delay on Frozen Javelin?

[ex-vault13]

It's not exactly the most overpowered skill in the world, what with infinitessimal increase in cold dmg. already acting as an artificial constraint from relying too much on its' freeze mod. As it stands, FJ is more a support skill which, when I get to LF, won't hardly be used anymore. I was hoping to max this and make it my primary killing skill along with Burning Javelin since these are the two new skills introduced in your fine mod
