Inferno tactics.

300 - 400 demons? You can even have a couple of thousand. Know how? You create a map where large armies are stationed, and you run around using diplomacy to gather them, or you set their disposition to be friendly, and that's it. I can do that too, and it doesn't require much skill.

Before you throw around unfounded criticism, based solely on your personal opinion (which may very well be wrong, don't you think?), try playing against Anton. Honestly, knowing him a little, I wouldn't bet on you :D I myself used to think a lot of things before I started playing online seriously. I used to think everyone was cheating, until I started analyzing saves more seriously (sorry, but when a player starts with a Conflux and arrives at your castle on the third week with 60-70 Minotaurs and crushes you, you'll start to think). You need to take your opponents more seriously, with respect.
