My point was about the scott being difficult to counter. Not USF viability in 1v1. The problem isn't that Ostheer need "I build this, it counters your unit easily." The problem is a lot of the USF roster is so strong it does that to other factions. The biggest offender is probably the jackson and pershing.
Scotts don't need "lucky shots". Use them like brumbars and bulldozers, attack ground and the shell goes where you want it, and the projectile is so fast it works very well.
But uh, if your best arguement to kill a scott is to try and charge a 60 range mobile howitzer with pschrecks in 1v1 then I think you should probably concede on that...
What you say doesn't make sense for this topic, What the value of "The problem is a lot of the USF roster is so strong it does that to other factions", the same argument can be made for every faction (minus UKF atm).
Scott need a lot of investment to be fielded and protected, you are actually arguing that 260*2+400 Manpower and 75*2+140 fuel is difficult to counter, yeah no shit Sherlock!
Even more if we take the scenario of 2 jacksons covering 2 Scotts. But hey, that's also 34 Manpower or 48 in the second scenario, nothing to be seen here, 1/3 or 1/2 of the USF army is difficult to take out with a single Pzshreck or a panther or a Pz4, oooh that's so abnormal! hell, he may have mined as well! Let's not forget that on top of that he may have call…. a Pershing.
To the OP, solutions have been given: play aggressively, do not cluster your army in one spot and use your tanks with proper support to push from different angles.
Last but not least, Ostheer has a lot of good doctrines with different approach to support your strategy: Tiger, Elefant, Pack43, Scope, Smoke and the best of the best: Ju-87
