I think Graf used that before me. And I've definitely seen other people do it, just not all the time (like only when someone is really late).
Is the thread not staying highlighted for other people, btw?
Well, you have plenty of encounter and at will powers to use too.
Most of your dailies aren't really a replacement for your other powers - they're somewhat situational. Let's take a look:
Victorious Surge and Relentless Assailant have pretty much the same function: they're powers that attack and can heal you at the same time. These powers are great when A) you're seriously injured and B) when we're out of per encounter heals (or near enough).
Carve Initials is some single target damage and an unbreakable mark. So if we really need someone to stick to you or if you need the extra damage from a daily power but not healing, then this is good.
Linebreaker Assault gives you Resist/All for a turn. So it's good when you expect several enemies to be attacking you. It's not good when you're spending an AP or if you've used Blood Iron - because then you'd already have more DR.
So deciding when to use your dailies shouldn't be all that hard.
