Another great spammer is RPE. Redox Packet editor. It is great but a little bit more complicated to use than Breakneck. It is however a bit harder to use than breakneck, but breakneck is just drag/drop & hit the hotkey. With RPE, you will have to create or download filters (similar to WPE).
What it does is it helps you to spam skills. Unlike breakneck, you can control which skills you want to spam and you can also change the speed/delay of the skill. So it’s better than breakneck in the sense that if you do not want to skills like cloak or poison react to double spam, then you use RPE!
Once you have gotten the hang of how WPE pro works, using RPE should not be an issue for you.
I have now uploaded rPE along with several common filters which are all included.
