You know, I'm going with no.
If you think about it. Giving a little to the weakest classes in the game isn't a big deal and in this case it's aimed towards using those semi-unique mechanic more than once-a-never in the lower levels when you cannot afford to "buy" more uses. Or at least that's where that little cheap wannabe fix is coming from.
Now you have several mechanics there that actually tapers down.
Encounter 1: Rage + Wild Scream + Feral Trance + Shifter
Encounter 2: Rage + Wild Scream + Feral Trance
Encounter 3: Rage + Wild Scream
Encounter 4: Rage
Or via mixed use lets you have 2~3 of those effects for every encounter. And this is excluding Waretouched Master which will add even more.
You're not lacking your
primary feature, you're lacking the
ability to nova every encounter which is another story entirely. So, nah. You'll be fine.

@Risada,
Like other spontaneous casters, using a metamagic feat changes the action required to cast a spell, however the Blue Mage may still gain the benefit of the quicken spell feat.
