I play a fair bit of team games. Currently ranked around ~50 in 2v2s with axis. I have not found emplacements to be the problem some people make it out to be.
They are mostly a problem in larger team games 3v3 4v4 when combined with cancer commander and suitable map types. That being said it generally takes more effort/micro and risk to counter emplacements than it is to build and protect them. Which is why emplacements are often harder to counter for lower ranked players such as the OP's skill range (no offense)and why higher ranked players don't have as much issues with them.
