The BLM thing isn't a script, or a bot. It's a simple disable of a certain animation that allows you to hit those spells a little faster. It's easy to duplicate without script or bot software. Combine it with lowering your crits and alloting all points to spell speed. Really simple stuff. Simple enough that I'd call it a low level exploit, so easy, not even worth being called a hack. But most of the other stuff you're calling out is mostly BS.

Love how people see somebody stop due to lag, and watch them shoot across the map and scream hack, when, actually, internet traffic stops being received from the server for a sec or two, and when you finally do get a packet from the server, their position has changed, thus a character shoots across your screen at a rapid pace, or just disappears to re-appear somewhere else. That's lag through and through. Has been here since the internet, and if you quite honestly don't know what lag is, then you aught not to be playing games online.
