One more thing to say, then I will complete my departure from pw.
Changing the shield skill would add a bit of a forcefield, so how about throwing weapons? Many times I've wished for a throwing axe to take out a pesky archer.
Feel free to tell me how I'm wrong

or how adding them would create lag, or create a time paradox and break the fourth wall and etc.
Make sure to remember this so one of you arseholes can quote me when I play pw again.
