I get that, perhaps i didn't make myself clear on what i was thinking about. (Was still a bit asleep back then). Aodhan above explained it a lot better than i did, it would end up being more effort than what is worth.

Either way, i really don't think a merge of Sheltron/Intervention is a good thing. For an example, myself and a couple of friends who play paladin use intervention with a <t> <2> macro for convenience, but if both were merged we would still end up with another button anyway (A <2> macro). It ends up not changing anything.
