No, the attack was lame. It was designed around and depended upon not being seen. There is no difference in gameplay between what they did and doing it in offline mode.

You are looking at the mission(s) from an extremely narrow point of view. HTC has every opportunity to make "not being seen" completely out of the LWMA equation. Fortunately / Unfortunately for some, the only thing I've ever seen HTC do about these horrible NOE missions is to make them more difficult.
Stealth is a major huge big giant piece of the warfare pie. This is a war: Part game / Part Simulation, air, land and sea combat with all participants given the opportunity to make modest, temporary adjustments to the enemies "support" capabilities (strat down times).
IT IS ALL PART OF THE GAME Your

particular demands for method of game play are part of it as well... "part" of it.
You don't have to like it. Whether this type of mission is used to hasten the "win" for a particular side, or perhaps halt the inevitable horde doesn't matter. What matters is, it is
effective.
I for one am impressed.
