You were clearly upset when you wrote this, but take a deep breath and I'll see if I can look through your match tonight
Before watching I can answer some of your quiesitons up front.
For the 222 I agree that this vehicle is in a bit of a strange spot at the moment, because its main job used to be hunting down snipers and it is horrible at doing that at the moment. In general you should use it like a recon vehicle decent dps at range but also very vulnerable. only close the distance on retreating units, even lighter vehicles or isolated infantry without access to snares.
One of the things that you criticize is in my opinion also one of the greatest strength of this game, this being able to craw your way to victory from the brink of defeat. You are obviously having an advantage when you are ahead on ressources, but you should never feel safe before the second that the match has ended. some good play, flanks and a dabble of blind luck and RNG can turn a match very quickly and you need to always have this in the back of your mind and thinking ahead, not on what unit would be nice right now, but what unit will be absolutely wital 3-4 minutes from now.
The player base certainly would benefit from a few thousand more regulars, but I would say that the balance is still fairly decent unless you are in the absolute top or bottom of the game. It has most of its players in the european time zone, so for optimal match making you should check in at european post-work/school hours. But also both the US and Asia has a decent abount of players so horribly unbalanced games should be the exception rather than the rule.
I can't say much more untill I watched your game, but for future reference (and to keep in line with forum rules), you should post your replay requests in this thread
