Combine actions without macros

[Guesswhat]

Is it even possible? There are some obvious actions/skills that goes hand-in-hand.

TL;DR: Having 2 actions-in-one buttons without macros would be awesome.

Raw Intuition + Awareness, Vengeance + Bloodbath or Blood for Blood + Internal Release.... etc. As I'm using controller, those cross-hotbars gets easily full, which makes combining some of these with macros an option to ease the load off the hotbars. However, seemingly more often than not the skills don't triggers as intended in fast paced, lag prone battles. In certain situations you really just want to quickly use, for example, Blood for Blood + Internal Release while continuing your skill-chain. In this example I find that this macro fails very often:

/ac "Blood for Blood" <me>
/wait 0.5
/ac "Internal Release" <me>

What occasionally happens with this is that only 1 actions triggers. Which renders it unpredictable. Increasing wait to 1 sec (wait-inline even) doesn't seem to make any difference in my case. In fact, it makes it worse. Removing the "wait" kinda works, but then you have to mash the button, and even then it seems laggy. And, imo, it's easier to press two buttons to get off 2 actions than mash 1 macro to get off 2. I'm guessing this is because macros can't queue skills, which feels much smoother.

Basically what I want is actions that triggers 2 or more "normal" actions, without macros. To make them go smoother they have to be actual actions. One obvious problem here is that this could create about 100 new actions lol.
Edit: Oh, and another obvious problem is that not all skills/abilities have the same cooldown. Still, I wouldn't mind just picking the longest cooldown.
