well reading thatyou sould be able to kick his ass every game because u no exscaticily what hes goin to do.
i hate the aoen but they are the best for cracking turttals and that is what yr m8 is rush to tech 2 biuld some gunships like 2 and then send then to hurshass his exspantion massexstractors thsi will cripple him and slow him down to a grinding speed so he want to be able to get the colloasal resouses needed for tech to
so the stratigy is provenent him from getting the resouses needed and so take the MEXs by his base and renforce teh gun ships with more units u can iver use artilary on his base or build factorys by the MEXs so he cant get them bk and start kicking out lots off units
also be quick because he wins thought *** loads of resouses and that takes a long time so play fast paced and not slow so he cant biuld up to be a monster
also all else fails use the aeon tech 3 arti because that has the best range for arti in the game except the mav and also the damge is very gd on the tech 3 arti hope that helps :P
