Running this in your 3.3.5 Windows wow.exe binary will remove the hunter auto-shoot deadzone of 5 yards.
To make abilities also have no deadzone you need to update the SpellRange.dbc flags from 2 to 0.
Code:
binary_pattern_replace.exe wow.exe "?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? 55 8B EC 8B 41 08 8B 50 08 C1 EA 04 F6 C2 01 74 06 5D E9 ?? ?? ?? ?? 8B 45 08 8B 4D 0C C7 00 00 00 00 00 C7 01 00 00 00 00 5D C2 08 00" "83 3D CC 97 D3 00 4B E9 83 01 00 00"
Code:
binary_pattern_replace.exe wow.exe "75 0B B8 01 00 00 00 8B E5 5D C2 04 00 33 C0 8B E5 5D C2 04 00 ?? ?? ?? ?? ?? ?? ?? 55 8B EC 83 EC 08 56 8B F1 8B 86 D0 00 00 00 83 B8 14 01 00 00 00" "B8 00 00 00 00 75 0D 0F 84 71 FE FF FF 74 05 B8 01 00 00 00 8B E5 5D C2 04 00"
