It's just moved the pay2win from gold ammo to premium accounts. People with premium tanks/ammo can afford to shoot premium ammo a HELL of a lot more than free players.
As has been discussed to death on the forums and on here above, all it takes is for everyone to carry 5-10 rounds of premium and it pretty much negates armour in the game. How many times in a game could you take a shot, but don't as you know you almost certainly won't penetrate. It's not more than around 5 times per battle I would wager, and that's all the premium ammo people need to carry, and just use standard ammo for all the other occasions.
Hull down T29? Hey, instead of having to think about how to flank and get round behind/beside them, you just turn off Mr. Brain, turn on auto-aim, switch to gold and open fire. I really enjoy playing my Pz B2 740, I like the fact it can take a lot of punishment but the weedy gun means that you have to really make use of weakspots and know exactly which targets you can and can't take on. A Hetzer used to be a very dangerous opponent to me, requiring tactics to flank them or a brave move to take out their tracks and get round behind/beside them - they're pretty much impenetrable head-on. No more. Hit auto-aim, put something heavy on the mouse button and go make a brew.
This is easily the worst decision WG have ever made (and I'm not one of these 'oh noes, teh Wrgmamng are teh evills!111'). It rewards stupid, lazy gameplay while punishing those who play intelligently and use angling, terrain and armour to avoid taking damage.
Bah, demo ran out for me. I might end up buying it as my three-year-old has got hooked. Where's the cheapest anyone's found? It's on Amazon for £15.
I enjoyed the detail with the Eurostar crossing, although I'd have like to have to park properly on the train and then have it move off. Same with the Ferry crossing, I'd have liked to actually drive onto the ferry and park.
There are HUNDREDS of tracks now and a whole bunch of different trucks. The main addition is moving parts and pistons which can be activated by the horn.
You can still play for free, but you can only play one truck and tracks that don't include the dynamic mechanisms. You can still watch replays of those levels though.
But after about 2 minutes of motorway driving, I was racing the other traffic and it took me about a further two minutes before I felt obliged to see what would happen if I went straight on at a corner.
It just feels really alien, not going as fast as you possibly can, all the time.
