I guess it depends on the support. I mean, it is pretty brutal when Omega Leader and Vessery lockdown a target.
It sure is, but what happens if OL is killed before Vessery fires? What happens if OL kills the target before Vessery? What if you didn't point Vessery's guns at the more important target because you couldn't TL it with OL? There's a dozen little inefficiencies that get introduced by his ability.
Don't get me wrong, it's a great ability, and he'll be brutal, and while heI get punched way above his points in a squad, there will be a fair chance that squad as a whole is a little less efficient because of the extra coordination you need.
The thing is, Vessery has a LOT more viable wingmen now and when Imperial Veterans releases. Like I've said, my current Vessery squad uses 3 FOs. It will be interesting to see how the V1s work with him. Also, haven't really tested him out with Advances yet either. Bomber could be a possibility as well.
