I know this was asked before in the thread but it was never answered. Aside from healing, what are the exact defensive and offensive bounces gained from picking up those medical supplies?

I looked it up (10 months ago). Maybe that helps.

I really can't say if the stats I cited back then are still the same. I currently don't have the game files unpacked, so I can't look it up either.

I don't know about CoH2 but when we played 3v3 or 4v4 in CoH1 with a wildly mixed skill team, there was only one real problem in that the AI cheats. I'm not talking about the resource bonus or anything because the "hard" AI that replaces players is really too stupid to do much with that.
The problem was that the AI would use pios and other small units combined with its knowledge about player unit positions to sneak through lines and capture cutoff points on non-Scheldt-style maps.
For some players this distraction is a lot worse than just having an increased amount of units thrown directly into their killing zones. I can only guess this is the same "problem" in CoH2.

The answer is to get better at the game but until then, actually having light vehicles (and using them to hunt those infiltrators, US ones can even recapture) instead of just static units and artillery should help. If you are higher skilled than your team mates, picking up their slack in this department should be your job. They probably won't learn much but at least that way they can enjoy the game without being stressed out about sneaky units.
The game simply can't decide if it should replace a player with easy, normal, hard or expert AI. In any case this would probably just create more problem. Hard AIs really aren't that hard to beat. I absolutely believe their game impact can be higher than some players' but that ultimately isn't an AI problem.

So what about spawning it with a 20 mm gun, so it is slightly more effective against infantry but sucks against all armor until you upgun it to its current (worse AI) state for XY munitions?
It would up the overall price of the unit for AT purposes and there'd likely be one less Panzerschreck squad (or less mines) around, too.

Its stats aren't bad but I think the price might be deserving of a slight adjustment. The 135 fuel equal 202.5 fuel for a non-penalized faction. (Not taking into account fuel conversion, in which case you're basically paying part of it with munitions. People tend to forget that).
So maybe reducing it to 120 fuel or so would put it in a better position.

Some RNG can be good: https://www.youtube.com/watch?v=-9ZI9kMsvRQ

However, some binary effects can be caused at random. What do I mean by that? An effect that either applies with 100% of its effectivity or with 0%. In theory those are ok with a large sample size but by the game's nature the sample size can be pretty small. In a large sample size it will work in your favor just as often as it will in the enemy's but this game has very small sample sizes: For example, the opportunities to AT-grenade a tank may be a few times per game and you normally only play each opponent once on the ladder (which itself has a massive sample size/population size problem). So if you AT-grenade tanks in a match 4 times, it is well within possibility that it might just bounce 3 or 4 times, which can very well massively diminish your probability of losing the match.

For example, some large explosives can have a tendency to miss completely (0% or very low damage) or to completely wipe the squad (100% damage). We've all had that one T-34 that completely misses that infantry squad for 3 shots in a row and the next game we might have one that fires 2 shots and wipes 2 squads with it.
In general the reinforce mechanic and squad size is a comeback mechanic (and a comeback/allowing for comebacks/recovery is good). But by that coin toss, the whole comeback mechanic can be circumvented by pure randomness.
Same counts for tanks' hp pools and repair abilities: They allow you to come back even when you had a few unlucky armor penetrates (randomness factor) in a row simply because the tank's hp pool is so high. With skill you can adapt and flee, repair and come back from a lost battle. Imagine tanks had a 5% chance to spontaneously combust when hit, that would kinda be like some lucky explosion rolls against infantry squads. It would decide games.

Engine criticals are another example: The tank is either affected completely (slowed), not at all (driving at normal speed), or by a very small chance devastatingly (cannot move at all or just barely). I would prefer a system that would either vary its effectivity (so e.g. a slow effect can slow it 20-60% instead of the static numbers) or a varying duration (overheated engine, cools down after 10-20 seconds).

However, I think some effects like the engine criticals are embedded so deeply into the game that changing them would completely wreck balance and unit design of many many units and changes to those are therefore unrealistic. But other things like big explosions can still be fine-tuned to be less extreme and more consistent.
Of course there would still be a randomness involved, at which point player skill can really shine (retreat at the right moment etc).

Are changes likely? I don't really think so.
