its not speedhack, its just a wise way to use your SP in your BM2 mode.
usually kasi, pag normal attack sa warrior pag naka BM2 ka is 4 lang then stop sya, parang hihinga then 4 ulit. well we can break that pause and utilize more of the BM2 SP remaining.
whatever your hotkey for normal atack is... do
normal attack--->esc----> left click----> normal attack
