Depends on what your facing and what faction your playing, as soviets with conscripts an un-upgraded M5 can be quite strong since you will almost always win the attrition battle especially if the cons have any sort of upgrade(SVT, PPSH, dropped weapons).
As Soviet with Penals, USF or UKF it is probably better to upgrade the M5 since the reinforce cost is so much more despite the infantry being stronger. You might win some engagements at first but the heavy bleed required to keep the pressure up may begin to delay your tech.

All advice given was assuming blob vs blob with no time to put down sandbags, MGs, offmaps, arty or any other call in ability.

My side got to be pretty one sided about halfway through the match, however enemy did manage to pull off a couple radio silence flanks that wiped a few units. We were dominating early game so I was able to get KV8 out at 14 min mark, got several good pushes that enemy never fully recovered from. However other side stalled for heavy tanks which allowed them to win back their side. Some good pushes from KV8 forced some reactions while ally bombarded with B4. Eventaully caught a KT out of position so RAM and mark target allowed for quick work and eventaully team surrendered.

I agree with most of what you say if not all. Another issue which hopefully is addressed in COH3 is upgrades with no downsides specifically on mainlines. Why wouldn't you get 7mans, LMGrens, G43 Pfussies and so on, they can snare fight off infantry and provide other utility such as flares or sandbags which is hard to balance. It pretty much makes most elites useless and the elites that are used are usually broken in some way. Using Guards as an example, it can scare off lights, button vehicles with its no downside upgrade and keep efficiency by merging with conscripts. Doing this with shocks is foolish due to loss of armor and horrible Rec ACC vet since they are balanced around having said armor.
I hope they make elites or infantry in general similar to Airborne(Assault)Guards/Paratroopers, these units have multiple upgrades for short/long range or AT. You gain something while also losing and for USF the doctrine gives Paratroopers either demo or mines. These changes add some more choice and thought to what you want to do and how your enemy needs to respond.

Used soviets as an example due to most agreeing they are the strongest or tied with OST.

Haven't made them for a while so I decided to scratch my itch. Eventually got them to Vet3 so they turned out ok.
The guy lined up against me went command P4 with PG Shreck/LMG Gren blob. It got me pretty good at first T34 wasnt consistent enough to kill so went back and forth until he got caught with a double team.
I also got a panic puma with a RAM, and repaired the T34 to RAM another day. Got a few RAMs for my teammates to finish the job.
Once my army got settled down and I got Su85 his blob tactic stopped working. Used Katy to bleed him and Dshka to slow down pushes from him and his teammates.

I always get excited when I play with a fellow member. "Him, him, I know him"

Decent game, we started strong with good control of our fuel and middle. Our team also pushed their gas pretty hard, they gave up on pushing our gas and started doubling Fox to wrestle control back. I decided to go for KV1/Guards to put down bunker and lay mines in case I had to keep pushing/flanking. Saw an oppurtunity and attacked OKW med base destroyed it but lost a squad. We were fairly ahead at this point that USF player got a little careless and got their stuart stolen. Annoying but fairly easy to push back, I managed to get a KV1 out at around 13mins and USF got Sherman so we were still in dominant position. We pretty much bully them until they start to roll out panthers/P4J. They finally start to get things going their way as they avoid our gas but double far side of map. Eventually Tiger/TigerAce/KT hit the field.
Game is slightly in their favor since my KV1's are unable to push reliably so I try to bait them to attack me but they are to cautious. I eventually see a chance to attack half health Tiger so I rush my tanks in while USF backs me up and UKF keeps KT busy. I lose both tanks but we kill both Tiger/TigerAce, Panther and a few units. I have a massive stockpile so I rebuild tanks and we keep pushing to close out game.

We probably could have closed out game earlier if I had committed both my KV1's earlier but if I failed I would have been left with nothing.
