The simplifications facilitated by lattice techniques are one of the main features. The non-perturbative nature of QCD makes it impossible to do many calculations that would be trivial in QED. As two strongly interacting particles are separated, the strength of their interaction increases, which is the opposite of everything else we're used to. In QED, you can often safely consider the first few feynman diagrams to be a good approximation of the whole process. In QCD, infinitely many feynman diagrams contribute non-negligibly to the result, which is why traditional methods fail.
