1. Ditch the whole vehicle crew popping mechanic
2. Add crew repair ability.
(3. Chance for crew to survive on vehicle death.)
Problem solved.

In my humble opinion:

• reintroduce three-point turn on vehicles without tracks
  
• prevent vehicles to turn first -> then accelerate, for orders other than rotation, or very very close destinations
  

1. Support your tanks with infantry.
2. Don't rush your tank into the fog of war unless you're completely sure of the enemy's whereabouts.
3. Keep your frontal armor towards the enemy.
4. Always reverse your tank if retreating. The times you save time by turning around to utilize your forward speed are little to none.
5. If you want to repair, unless you're completely aware of the enemy's position, pull back to the base.
6. Don't chase to finish off tanks. There are some times that you think the trade is worth it, your tank for his, but you need to give it a second thought.More often than not, the trade is not worth it, for many reasons.
7. Stop your tank before firing a shot. If you're moving you are receiving a 50% penalty to your accuracy, which is obviously bad, especially vs already hard to damage axis tanks.
8. Use your tank for it's intended purpose. Don't try to penetrate panthers with the Sherman (even with AP rounds) nor build T-34/76s to fight tanks head on. Keep your tanks on their designated job, and use your other units to deal with the rest. (For example keep your sherman on HE shells, ignore the enemy PanzerIV, and keep clearing those squads. Use bazookas or AT guns for the panzer).
9. A snared/fausted tank is a dead tank. Be sure to have repairs nearby and, more ideally, keep your distance from infantry that can destroy your engine.
10. Sweep for mines before you charge in.

That's all I can think off right now. Have fun

Rocket Artillery. Skip your light tank and rush that rocket artillery. That is if you aim for a hard-counter/deal-sealer.
If you want to control the blobs double up on MGs. You can't expect to control 4-5-6 squads with just one of yours. Use 2 or 3 MG teams until he gets the Stuka zu Fuss, then forget about the MGs and go for the rockets.

That said, you still have to keep the pressure up during the whole game, to keep the blobs to a minimum. If you give your opponent space and time, he will blob up.

1. According to your play time, balance doesn't affect you, no offence. You should stick with CoH2 if you like the style/setting, you won't find it elsewere. Try to polish your gameplay
2. If you insist, and don't mind changing the setting to something futuristic, try Dawn of War II: Retribution, with the Elite Mod. Amazing competitive mod, with an equaly amazing mature community, regular balance updates, tournaments, etc The only drawback is that the game is relatively old, so the engine is a bit outdated mechanic wise, for example there isn't a 'reverse' command for vehicles, stuff like that.
3. Starcraft II is hard, but it has more players and therefore you are more likely to get matched to opponenets at your level.
