Quote from ubermanDepends on the question; how do we beat WyzDM? or how do we beat chaos?
Its not one question.
how do we beat WyzDM?
Most of us dont, if he's playing order or chaos.
I have played my chaos vs his order, and would you like to predict the result of that?
How do we beat chaos?
On short map sword rush. FULL swords, not half hearted rush.
On all others, wall and archers, add a mage ASAP, defend until you can add spears and merics, and then advance to tower.
Secure tower, get spawn and attack.
Just to expand a bit on medium or long maps -
I mean archers not castle archers and wall, secure defences behind the first wall to stop the bombs, a wall and few archers is hard to break early game as he's beating on your wall you are beating his units, and despite the order belief in OP chaos regen, it takes a long time for a jugger to heal up.
When you have a few archers, try put a wall closer to tower. Stay behind it to kill next spawn, but then mount counter attacks to try chase his wounded units from tower. If he attacks, kite back to wall.
If he breeches far wall, kite back to original wall.
Add a mage ASAP, and then a meric plus an odd spear to the defence - use spear to protect the wall, and meric will heal him so you dont lose the bomb-proof wall.
Your electric wall and blast should make it really hard for him to beat on your wall without heavy losses, and take out tower spawn with minimal trouble.
Keep trying to beat him off tower, while building a shed-load of miners behind your safe wall.
Build a giant to add some stun to the defence, each attack will now cost him a unit at least, due to stun keeping one unit from retreating.
Build an army of your choice around your giant, archers, mage, meric and spear, then attack (with tower spawn to tank the ineffective castle dead).
Unlike you, he doesnt have AOE castle archers to hit lots of your units at once, nor does he have walls to hold you stationary for his aoe spells - he cant defend anywhere near as well as you can. He has no serious counter to your Egiants, and if you keep the pressure on, your healing is far faster than his regen.
TL-DR:
Defend FIRST, set up eco, take tower, build superior army, storm his laughable 'defences' and win game
