Totally agree with that Gyphin. Although you could say it's unsporting to play against the AI period and I wouldn't disagree.
But if you are playing the AI, and you want a good tough fight you shouldn't use the training facilities at all, because if they use them it will be by accident. It should be easy enough to get them to build the facilitiy, but I don't think they can make the decision to park their fleets in orbit to get the benifit of them.
If an agreement is made for a specific game to not use them, or to only use one per sector, then by all means you should abide by that. But noone should assume that agreement is in place, or call someone a cheater for doing this when it has not been prohibited.
