A dict can be a very viable netting strat IF you are running a hardcore land trader and taking advantage of the dict GA benefits, otherwise dicts are primarily a war strat. In fact, most people planning on warring with a dict will run it as a monarchy until just before war season starts to avoid the onerous construction penalties.

Commies have 8 T-10 finishes, but no wins. Even people that gain land as a dict would never destock as a dict, but they have had many good finishes destocking as H or D. If you run a commie like slagpit and are not concerned with trying to win, just getting a good finish in a novel way - a commie can be a viable netting strat - but for mere mortals, its a dead end netter.
