The way to get more frequent updates is to change your sources.list to track Debian Testing instead von LMDE.

Tracking testing will have negative effect on stability of your system as you are prone to encounter one or more buggy packages sooner or later. There seem to be bigger problems with Cinnamon than with Mate.
However the current update policy to only publish 2 UPs per year in my opinion has negative effects on security and recent UPs have killed several systems which is not what I call stability. LMDE sadly seems to change from semi-rolling to stumbling.
So you have to decide what's more important to you, stability (which means to track LMDE, use the current LTS-version 13 or Debian Wheezy) or security (which means to track Debian Testing or leave LMDE for some other distribution, new Mint versions from 16 onwards skip most of Ubuntu's kernel updates so they are no option in my opinion).
