Why the game isn't ballanced?

Gathered my experinces since the game launched and I want to hear my fellow's opinions about these points:

Why the soviet infantry don't stand a chance against grens with lmg.
http://www.coh2.org/topic/8240/very-few-cost-effective-counters-to-upgraded-grens

Why soviet has missing hard-counters or only accessible via commanders.
(Guard infantry for example.)

Why the Elephant can't be countered without sacrificing too much men and vehicles and why the soviet late game call in vehicles (IS-2, ISU-152 one-shot a german squad?

It is sooooo stupid that a tank can blitzkrieg away with a damaged engine, isn't it?
120mm mortar and the B-3 203mm Howitzer is joke how it kills everything.

Why the T-34-85s are expensive and bad?

Where are the basic defences?

Why pop cap is 100?

Can't we just decrease the RNG factor somehow: 1 mortar shot into a building and it goes down killing the squad(s), and sometimes it takes like 10 shots to destroy it. Same with the grenades.

I won't mention input lagg, penals, maps and lack of lobby, 'cause everyone them.
And finally before the shouting starts how noob or fangirl am I look at this please:

3v3 &4v4 is sad

germans sure have learned to keep their tanks alive

they're limping behind till the last quarter of the game

once they reach critical mass its tankrush with panthers

let's look at how each tanks are designed. the elefant are specifically designed to destroy other enemy tanks and it has incredibly think armor but is slow as hell.

isu152 is a mobile artillery piece so it counters everything, but has very weak armor. so a good tank flank can get around it.

the soviets designed the is2 to counter everything hence the huge splash damage but in turn it can't take on the best of german tanks.

i made a lot of suggestions on t3485s... but relic still hasn't implemented them :'(

To be fair good balance takes time. I'm sure they are aware of this stuff, but if they change everything at once people will be more mad than they are now.

I think they are doing ok so far in terms of balance.
