You can also bind almost every key bind with, for example:
1, 2, 3, 4, 5, 6, q, e, r, f, c, x, z, v, g, t
And than repeat the proces with:
Shift + 1, Shift + 2, ...
Ctrl + 1, Ctrl + 2, ...
Even "Alt + 1, ...", but i doubt ul need more than Shift and Ctrl.
That way u can use 1 for Intercept, Shift + 1 for Heroic Fury, and constantly see the CD of both spells (using a cd addon i guess), since im not sure that the macro can provide u with 2 diferent CDs on 1 button.
Mod macroes can be really usefull if u have a spell that u use on both main target and focus target, but otherwise i think its better to bind it to a diferent and similar bind so u can track the cd of both...
