WiC's MW Mod is a great mod for sure, on the basis of effort. But it serves as an exceptional example of mis-scaled units and their negative consequences associated with it. A fine example is their aircraft/Close Air support, heavy SAMs(Patriot and S-300) and ICBMs which literally turns the game into a crazy "dodge SAMs and ICBMs!" micro routine.
There are no ICBMs. But the short-ranged missile units and heavy SAMs are indeed a bit out of place.
Nevertheless, it was a factor still moving units of WiC, at least until recently.
In addition, that was the point of the game - simulation of a IADS. It didn't go perfectly, but the central thesis still stands - that a mod, sufficiently well done, can be a boon to the game.
