You should mention in the description of your BFS maps that AI is supported, and to what extent they are supported (which races they actually play). In other words, add a section for details about Computer AI players.
EDIT TO PREVENT DOUBLE POST:
My friends complained about overpowered units. I am merely relaying their message, and if you agree, you can go ahead and make balance fixes.
The KCombine race of the humans has the Marine, a tier2 unit that costs 5 food, with very fast attack speed on piercing damage rounding around 90. 600 range with the range upgrade. Tier2 for that much firepower? He also says that no unit in melee maps should have very fast attack speed unless buffed by a spell.
My friend also said that, in the Burning Legion race, the hydralisk is overpowered due to 130+ piercing damage with Fast attack speed.
I personally think its not as overpowered as he says it is, since its tier3 and takes so long to build. But i do think the hp may be a little too much. 700 is a little too tanky. maybe 600?
These are my friend's arguements. The only things I actually think are the sentences that I spoke out in first person. I'm sorry if you don't really like the balance ranting that is common in warcraft communities.
