As condescending as people can get about that yes, the game isn't supposed to only be balanced for the minority of top tier players. By definition most of the people who ever play (and purchase) the game are going to be low or mid tier.
Rank is not very important to understanding balance. Someone can have poor micro but understand the game well.
What is impossible is to form a balanced perspective of units if you never actually use them yourself and/or never play against them. Someone with 4 games as Soviet has no business talking about balance.
What's more, a lot of these fanboys for both factions say stuff like "When I play X faction, I don't feel Y unit is OP" whereas in fact they almost never play that faction at all.
When confronted with the fact that they have no experience of what they're talking about, they hide behind statements like "Even if i had ZERO soviet games I would still know the faction from the opponent posture." which anyone who has ever played both factions equally knows to be a false argument.
Anyway, clearly forums will always have fanboys and I'm glad that they're now starting to self-identify as fanboys so we can all tell the difference between them and objective posters.
