Well, as we know, modern armour didn't sell very well, which is why there hasn't been any follow up made of it. Which is why it's not on the poll. I'd like some more too, but those are the facts.
British armour has little chance of ever being made. It's taken almost 7 years to get a King Tiger, which i think is undeniably far more popular than a Matilda or Churchill, which is why there is no British armour on the list, save the Firefly, which was a very effective vehicle and arguably one of the very top sherman variants.
Pershing is on the list because it is a 'big american tank' and people who buy tanks at WM are more likely to want a 'big american tank' than something else, like a Stuart. It's also one of the few pieces of allied armour you can name that could take on the big german tanks head to head. The poll isn't a list of tanks in order of historical importance.
The Priest is very recognizable and has a pretty big gun on it...so that's why it's there and not a tank destroyer.
You're preaching to the choir here guys. I want all kinds of armour too. The poll is just to get a sense of what people would like to see NEXT and to keep hammering 21c over the head with the T-34, which i knew would win the poll hands down.
i never met an airplane i didn't like...
