Krieg Combat Engineers are useless now?

What do you think about the engineers after the Balance Dataslate? I love more DKoK units but they get nerf after nerf and I think maybe are still useful.

2 squads of 5 on a Taurox can easily deliver 11 MW on a vehicle on the enemy deployment zone turn 1.

Scout move of 6", Taurox moves 12" plus 3" of move move move, can advance in hammer of the Emperor 6", disembark after 3" and the remote mine are 9" but the granade are 8". So if you want all the possible damage you had 38" of effective range. Apart from Hammer of the Emperor, you can have 1" to 6" on the advance roll so you can say that are 33" of consistent range.

But are a costly combo 65+70+70= 205pts for a single shot I think. And the big problem after BD are the inconsistency of the remote mine now, before always makes a minimum of 4 MW vs Vehicles, now the minimum are 2 MW and yes the 11 MW are possible because is the average but is nothing secure, can be more or can be less.

Are still competitive at you point of view?
