I barely play chaos, so out of curiosity, what do you think is the best order vs order strategy on a long map. I already know a short map one so ovo on long maps

Get 1 sword 2 miners, and send sword to the middle. If the enemy has better stuff, run and get a archer and attack. If the enemy also has 1 sword, attack ,and if it looks like your sword will win, win and get the middle, and retreat if enemy has anything else. If the enemy has no stuff, get the middle and scout. Tip: Go for fast units like shadwrath, speartons, ECT. Don't go for the slow units like albows and giants. (still get mages and merics)

This is my 1800 rating strategy.

It is definitely Miner/Miner/Sword. It's got a good economy and you can use the sword to get tower and scout.
