Ok, if you have trouble with lvl 5 coms which destroy your precious porc, I have solution just for you!
COUNTER NUMBER 1: SCUTTLES!
Step 1: Bulid scuttle

Step 2: Get them close to enemy commander (If you suck at this, just give the scuttles to someone like Skasi)

Step 3: Click ctrl+D and say "Rest in pieces" (Should looks like this)

COUNTER NUBMER 2: SILETTOS!
Step 1: Bulid Silleto (or 2)

Step 2: Stun this noob!

Step 3: Ask Rafal for some help

-But what if enemy bulid more porc than me and keeps his com behind defence line?

-Well, Sfireman will do the dirty job...

-Seems legit...

See ya on the battefield. Keep calm and bulid anti-nukes :3
