Will you end up making throwing like archery?
Is it STR/DEX related for a valid reason?
Are you going to make weapon throwing recovery items to make up for the delay when throwing?
Are you going to make more weapons for throwing?
Or is it only a assisting skill? Unlike other dexers classes there's no way to kill someone with just a throwing dexer. Sure you can kill pvm things, but pvp it a totally different story.
