But it's a particularly shooty vehicle. You're getting your Av11 tank/5 T3 models within 6" how, exactly?

If I'm close enough to be in melta range, I don't care even if he has 2+ cover.
or since Dominions have Scout and maybe first player turn, maybe they were just in range. 3 scouting dominions (maybe even outflanking) should be able to get in range of something. The 2+ cover thing was in reference to being probably able to assault anyway at that point.
All of this pertaining to the discussion over Twin-linking vs Ignores Cover, granting that you can't assault on the first player turn or coming in from outflank giving more benefit to Ignores Cover, but not everything is always in cover so you don't always get an Ignore Cover benefit but you can always benefit from Twin-linking (barring hitting and wounding with everything, but that is like saying you get no benefit from Ignores Cover when they fail their Cover save).
As far as ranges the rest of the game:
Ignores Cover - 6" tank move + 6" disembark + 6" 2D6 pen = 18" (24" 8+D6 pen) still covers a lot of board.
Twin-linking - Same as above but they get cover save and you can't assault or 6" move + 6" 2D6 pen shooting + ~7" charge = average 13" threat range (8 - 18" possible) for assaulting or 12" shooting 2D6 pen (18" 8+D6 pen) still covers some board, and with 3 units on the board doing it makes it more possible.
Most of the pro-argument for Twin-linking was that it benefited both weapons of choice. The 12" range of the meltagun as a limiting factor of the weapon we are talking about using also limits the benefits of Ignores Cover as compared to Twin-linking due to being able to assault after shooting. You could still assault after shooting with Ignores Cover the occupants of the vehicle (if there were any), so it is not the worst thing either, but generally just destroying the vehicle is about 75% of the goal. You are looking to destroy a dangerous vehicle or expose the squishy passengers.
I guess another major benefit of Ignores Cover is for those Jetbikes and Bikes Turbo-boosting.
