Would it be possible to change the bar based on the distance from the target? For instance, when I'm at melee range from the target, one bar would be displayed, and if I move to ranged distance, it would switch to another bar. This would assist hunters in segregating melee abilities onto a different bar so they don't occupy space on the main bar.

in example, if Raptor Strike is in range, show bar 2, if Multi-shot is in range show bar 1.

im talking about wotlk/cata classic.

thanks!

This one isn't actually possible due to restrictions on Blizzard's end. Action bars can only switch on conditions that you could write a macro for.
