This is my Chaos vs Order startegy (my ratng is 2106):
Start 2 craw/2 miners.
Keep making crawlers and miners.
If enemy
-sword mass,make 6 crawlers and start bombs
-archer mass make 3-4 crawlers and 3 bombs and attack them.
You Need amazing micro.If enemy still sword mass,make 2-3 eclipsors to kill them,than make deads.Or if you start winning keep on eclips.
If enemy keep on archer mass,made some medusas (for killing mages),eclipsors(i beated Riddick like that) and giants(longer defend).
LITTLE MAPS:
If you battle enemy FIRST TIME start with 2 miners.Then,when first 2 miners (you got it on start) get gold,you will got 350 gold,than buy castle dead.Than keep making bombs(hide them in castle/behind statue) and just attack miners.If enemy got archer,attack archer.So keep making bombs and miners and fast possible get 2 deads,than jugger than deads and juggers.You will easy beat him :).
When you battle sam enemy SECOND TIME 2 craw/2 miners cause your enemy will think that you gonna do the last strategy ^_^ well he is wrong :).Than mass crawlers:When you make 8 crawlers make bombs and just keep attacking and kill his army ^_^.Later just kep on deads and juggers and he is X_X :P.
Well that is mah CvO startegy.I think it gonna make you little better. P.S. my English is bad :(
