I've recently picked this back up. I tried a few years back but was being whupped by Pay to Winners.
It's enjoyable but for some reason it's not really grabbed my attention. Which is surprising as you get to drive TANKS!!!! And I do like tanks
I suspect I need to put a bit more time in, get some practice shooting & moving so I don't get slaughtered so much. I'd say after about 75% of my deaths I'll realise I'd got so focussed in hitting the tank I was shooting at that I'd stopped moving or even using cover and I'd just get picked off.
Sometimes I'll roll out with my fastest light tank, blat around where I know the reds will be and see how many I can get spotting bonuses for before I get vaporised

I'm tempted to go back and try to level up an SPG now - maybe long range strategic fire will be more successful.
