never said it wasnt. but on the other hand, its not exactly in the realm of a Gaurd Conscript bashing Ghazkhull to death, either. I play Marines. i play Marines up-close-and-personal, because they tend to work better this way. true, a canny opponent can avoid getting their skimmers close to anything, but a solid net of units can make this impossible at best.
many players can and do forget the use of TACTICS... this is more than cut-and-pasting a numb-n*tz netlist onto your B-Scribe roster, this is application of force where needed. positioning of units, use of terrain.
Catching a skimmer in CC, or with an exposed rear isnt Rocket Surgery.
