Me and some friends started playing a few months back. Granted we are not above 5-6 games yet, but we have played with marines, orcs and IG so far. We also had some initial conserns regarding the first fire/snap fire dominating, but so far for us the close combat units are really shining. But its the close combat troops with high movement (orc bikes, IG horses/bikes) that are the real stars, in no battle have they killed less than their cost.
Its actually turning into a game where we have to give much more respect to mobile CC troops and start placing infantry as a barrier in front of artillery to screen it off etc. So our experience is almost the total opposite of your fear, there are alot of movement across the board and it often turns into a bloody melee....at least the way we play the game.
Im sure that if both buy a pure shooting army and are content to just first fire away all day it might play out as you say, but that has not been our experience.
Our only "complaint" so far is that when using the victory point system and at 2000 points (small battles to learn the game) its very hard to win on victory points and most battles have been to the last man standing so far
(yes, we place 6 objectives)
