Could you elaborate on the statement that chaos is stronger in top level play? And how would you balance it?
Pretty much what zomar said
A top chaos player can snipe all swords of an order player with pure crawler+bombers without losing one single crawler.
Swords animations are far more difficult to manage comparing with crawler micro, crawler micro you just need to keep running back and forth and removing out the weak one to regenerate health
For swords, every low health one you have to garrison , which will then get your swords sniped . Weak crawlers can still involve in battle, but weak swords can just garrison and make the army weaker.
Also, swords split and archer kiting requires heavy spacing to dodge the AoE bomber, chaos player don't need to worry about it at all, just either go for miners if the swords split, and go for swords that do not split.
Some order players may tell me not to use sword start but use archer start, I spent a long time to test on both . I can safely say, archer start is nothing better than sword start.
Deads always come out exactly same time as archer, and one dead with couple bombers and crawlers behind is enough to stop 3-4 archers approach. Once a row of deads are set up, what a chaos player need to do is just to get couple jugs, tower spawn, a medusa, then auto-win .
Castle archer is nearly useless against chaos, because deads player just need to make their deads stand in front of 2nd row of gold, to block all economy from the order player. And deads can out-range CA to destroy the spear/miner wall as well.
If a chaos player use wings, an order player can at least set spear wall + meric to tank it for a while. Deads stop any possible turtle/defence, as long as an order player gets spear/meric, all die within seconds . If an order player goes for ninjas, chaos player can stun ninjas with jugger charge, and even ninja kill a dead/jug, a 1v1 trade still favors chaos player.
Unless an order player can bring out deathball, otherwise chaos rape order.
Top level play, the top level is like 2.4k+ , like me/zomar/ otaku, we all main order for 2 years, and only played chaos for short period of time, but we stood almost no chance against each other's chaos.
For most other players , the game is actually very balanced for all three empires.
