Viability of Spectres in Multiplayer?

On other forums I heard about this discussed. I wanted to hear what the folks here have to say.

To sum up what was talked about in the other forums:

Make Spectres mutually exclusive with Ghosts so as not step on each other's toes.

Change the energy costs of Ultrasonic Pulse and Psionic Lash.

Specialize the two for different tasks.
Ghosts would stay the way they are now. With their abilities focusing on offensive support.
Spectres will have their abilities be focused more on crowd control and defensive support.
Some abilities suggested were:
Ultrasonic Pulse
Psi-Shield-Defensive Matrix
Swapping Psi-Lash for the Mothership's old Time Bomb ability that slows enemy attack
and movement speed.

Do the people at this forum have any thoughts on it?

 

Doesn't the Raven provide crowd control and defensive support? It has hunter seeker missiles and point defense drones which I think are pretty suited for that role.

But the thing is Ravens are tier 3 and if Spectres can be made at lower tiers I can see that getting 1 spectre early on in the game would be like the Protoss's Sentry. It would have the ability to hold off early agression with relative ease so long as it has energy. But then again Terrans have bunkers so I don't really see how the Spectre would fit into the Terran arsenal :dull:

 

I don't really use the Raven often myself, but it doesn't seem to be "defensive" when it shoots missiles and drops turrets. The only purely defensive ability it has is the Point-Defense Drone

I also have to disagree with you on the bunker. The bunker, like the photon cannon and spine/spore crawlers are mainly used for base defense.

Its fitting that you mentioned the Protoss Sentry, because I believe that the Spectre can fill a similar role as support to an assaulting force.
