Please help me, i need some advice about 3-5-2 upside down V shape

[Star Falls]

Hello everyone, i am new here, anyone can give me some advice about my tactic.
Here it is:
AT-AT
AC ^ (arrow up)
MC^-MC^
DML-DMR ( arrow down)
3DC
And this is my result:
I found that i gain advantage against most formations. But i struggle against
AT - (or 2)
AMR AML
3MC
DL-DC-DC-DR (or 3 DC in case of 2 AT)
Or people who use:
AT - AT
MC-MC-MC
DMC
DL-DC-DC-DR
And the last one:
AT AT
AMC
MC-MC
DMC
DL-DC-DC-DR
I found that my attack is extremly weak while playing against opponents who use these formation even if they are much weaker.
