Double nano double gun ACU can kill an ML easily (or a chicken with decent micro), nothing short of an investment equivalent to that is killing it so bringing advanced nano makes the whole convo pointless.
Double gun counters:
- Total air supremacy
- Coherent firebase since lines of pds die extremely quickly to the aoe of the gun
- 5 snipers or competently micro’d percies (around 5k-6k mass investment) which can still be killed by the double gun ACU dropping on the units
Air supremacy is not tied to someone going double gun in a teamgame, hence relying on it is inherently risky. Instead you are left with the firebase option or having enough aa alongside your t3 army to discourage a drop on your supposed counter and resulting in you dying.
You don’t need a t3 pgen for double gun, so irrelevant point. The results of your investment is a won game as basically nothing exists to stop your push except a large concentration of bp which is usually only located right at the enemy main base.
If you’re looking at it from 1v1 then I have nothing to say because nobody seems to even use it in 1v1. Buffing it for 1v1 makes sera which is already probably the best all around faction in teamgames even more ridiculous just for the 6 dudes that even see the beginning of t3 stage in ladder. It would need a huge nerf like taking the aoe away to even be considered much cheaper than it currently is.
