Limit armies per territory

Maybe I am the only one. But it seems rather unfair for a person to deploy 30 armies on a single territory, only to "clean" everyone out.
Game 165570 is a perfect example. The Green was backed into Australia, no hope for survival, but he comes out with 30 armies and kills everyone. If it had been actual RISK he would have been eliminated.
Every game I have lost, being three (to no wins
) has been to people using this strat.
I know in the actual RISK game you are only allowed 12 per territory. I don't know if using the number 12 in a trademark infringement or whatever, if so use a different number. 15 would be good.
Anyone agree? Or am I a whining n00b?
