It is massively frustrating for a noob, once you gain rank it becomes much better though.
Flying is a POS, i don't even bother trying it, a large proportion of the pilots there do not know what they are doing either.
The tanks in it are brilliant, i love the GV aspect. Getting a kill there is so rewarding because it is so difficult in comparison to AH. Once you get used to the tanks, get the rank and have the patience to set ambushes etc. you start having fun, it is a lot more tactical than AH. Once you get the Tiger it is amazing, it really does dominate the battlefield like it did historically, it is satisfying when you start blowing off turrets and holding back attackers.
Infantry is not worth bothering with, your headshots would count if you were hitting him right, dont forget it is not insta death like AH tho - he could have carried on rolling for a long time.
I was a subscriber for 6 months or so, it doesnt grab me and make me want to spend hours online like AH does. It is a good tank sim and thats about all i would recommend it for.
