It's not a commander, it's not mobile; and broadsides are basically now little more than instant death able AA defense platforms...yes, I know they put out a bazillion shots and if you give them missile drones, they put out even MORE shots, but honestly I'd rather have skyray; It's not instant death capable, if you buy the dispod it's got a 4+ cover on the move, comes with it's own networked markerlights, has better range than missile broadsides, and doesn't need to buy skyfire at 20pts.
Just my opinion, but broadsides are no longer an anti-armor choice. S8 AP1 from across the board and no melta rule or armor bane? Not looking too hot to me.
