dude, srsly... you quote guys that say the truth and just say "not true", not even an explanation/counter argument.

That's because I am not discussing the quality of my connection.

As has been stated before, it is a shared connection. A drop rate of 40% is abnormally high, so it is very likely your connection has something to do with it.

It hasn't.

The Russian Zis is very good. It does the same damage as the Pak (dmg and penetration) and has the same range. It doesn't fire as fast but it has the very useful barrage ability and a huge crew, making it very resilient, even against weapons like a mortar or a grenade that are meant to take it out.

That's true, but as Russian I often find myself with an astounding lack of targets for the Zis-26. Vs. light vehicles I just play sticky nades/guards rifle and when the first PzIV/Ostwind rolls out around the 10 minute mark I can already pull a SU-85. That relegates the Zis-26 to an anti infantry barrage weapon, but why not simply get a mortar for the same price?

No, I am not talking about their looks. It's just that for 360 manpower they don't really have a good place in the game at the moment. I think they should be reduced to 240 MP in cost.
The reasoning behind that change is that I have big trouble to justify the purchase of Paks throughout the game.

Early game Paks are virtually useless, except maybe sniping Ostheer HMGs with the Soviet's Zis-26. But you can do the same with a SC while being aggressive at the same time, instead of being locked into the defensive HMG/PaK combo, so I see little reason to go that route - it also costs much more.

As soon as light vehicles hit you obviously want that Pak on the field, except that you don't. As ammo conservation is foreign to Soviet players anyway, you can just throw a couple of sticky nades or call in a Guard Rifle that does essentially the same job as the Pak while also being effective against infantry - at the same cost as the Pak. Again, you end up in a better position by not purchasing a Pak. On the other side as Ostheer the Pak is positioned a little better, since you're arguably hard pressed to find a counter against a fast T-34 or T-70 otherwise. The only viable alternative is a Shreck'd PG, the 120 ammo for that you most probably lack.

Late game is where the Pak completely falls apart, especially for the Soviets. A SU-85 costs less MP than the Pak and again does the same job but better. Since the SU-85 is the only fuel sink for the Soviets at the moment anyway, there is zero reason to purchase a Pak, except you fucked up middle game and somehow end up swimming in MP while being short on fuel (something which I have not seen happening yet - I am either short on both MP and fuel or can just churn out SU-85 like there is no tomorrow). I'd love to field some Zis-26 at this stage of the game, to support the SU-85 and especially against Ostheer infantry, but since it effectively costs more than a SU-85 I simply can't justify that. Again, the Ostheer Pak is situated a little better at this point, simply because german tanks cost much more than 360 MP, so pulling a Pak is actually a viable alternative, bridging the time to your next tank.

On the whole I find little reason to play the Zis-26 - while incredibly strong - there are simply better alternatives available throughout all stages of the game at effectively the same or even less cost.
The Ostheer Pak comes out a lot better, but then again it is so incredibly easy to decrew german Paks and they lack the punch of their Soviet counterpart against heavy armor while also being nigh useless vs. infantry.

Thoughts?

i don't understand what exactly you mean by "relics networking".
pretty much everything in the game is done via steam.

No.
