In general, though, the unit doesn't add much. Improved comms and a couple of Vox casters could obtain the same effect, and for fewer points.
His: 97 points
LD 10
Reroll Reserves
Hood
2 Flags
Yours: 55 points
LD 9
Sentinel with Multi-laser
Reroll Reserves
For 42 points, I think a 2nd Flag, a "chance" to stop psychic powers, and
LD 10 is well worth it.
Granted, you can get most everything this unit provides from another unit, be it Sentinel or
WH /
DH, but no single unit can do all these things for this cheap. There in lies the utility to me.
OTOH, I'm not sure if this unit is officially sanctioned or not so I wouldn't recommend it for anyone thinking about a tourney.
