GnomeSequencer-Macro Question

[jkalb]

I was wondering if there is a way to add more functionality to my macro. For example, since Plague Leech is the highest priority, is there a way that i can set it so the macro only uses it ONLY when I have 2 runes depleted? Also, cast Obliterate ONLY when Killing Machine is proc'd? I am basically trying to get the macro to do exactly what is suggested on Icy Veins. Here is a link to what I am talking about:

This is the Gnome Macro that I have created:

Sequences['Frost2H'] = {
StepFunction = [[
limit = limit or 1
if step == limit then
limit = limit % #macros + 1
step = 1
else
step = step % #macros + 1
end
]],
PreMacro = [[
/console Sound_EnableSFX 0
/targetenemy [noharm][dead]
/cast [nostance: 1] Frost Presence
]],
'/cast Plague Leech',
'/cast Blood Tap',
'/cast Obliterate',
'/cast Howling Blast',
'/cast Plague Strike',
'/cast Frost Strike',
PostMacro = [[
/script UIErrorsFrame:Hide();
]],
}
