Here's your problem: you're not deploying right. No change of your list is going to help you if your opponent can always play a 36" keep-a-way with his objective.
One of the things I've used in the past is the fact that even a single infantry model can now take/contest an objective. This means that if a squad is wiped down to 1 dude, and that dude doesn't break and run (regimental standard
FTW), your opponent is left with the option of wasting yet another precious turn of fire just to kill a single guardsman, or having that 1 guardsman be the one to hoist the flag over the objective. If you send a whole platoon at an objective, it's going to be difficult for you opponent to stamp out all of these little shattered remnants in time.
