Specialized smoke grenades, better overwatch, suppression capabilities, and extra movement speed aren't worth using?
And regarding light armor, I don't think any XCOM game had such stuff. Your default armor was the lightest possible, and it was nearly worthless. At least in this game we have things like psi armor and ghost armor, which offer lower health protection in exchange for other abilities.
They reference Armor types and only have two: Medium and Heavy (and they will outright state "heavy").
Anyhow the thing is Sirus. Is it more useful then anyone else's ability? (Heck the Heavy is a supperior offensive Support in everyway except that it is forced to use the heavy plasma.)
Also their extra movement speed is for healing not offense.
It seems to be a theme of Support. They seem to have lesser versions of everyone elses ability with the smoke grenades being the only thing unique to them outside of a healing support specialist.
Also Snipers have even better overwatch then Support, same with heavies.
which offer lower health protection in exchange for other abilities
Oddly enough... I think the ghost armor may be just outright better then Titan. Even at the expense of 4 health.

But still the question remains.
Is a support that does not go healing specialist (as in, doesn't get the extra medkits, doesn't get extra movement, doesn't get healing increase) a viable build?
