A few things I've noticed on vids.
The games are much quicker paced due to modern tanks being faster. Plus camping is very hard due to artillery being accurate. I think the earliest tanks are the 1960s.
Artillery looks fun, no more powerful than normal tanks but more accurate than artillery in wot, they also display a ping on the map when they fire which the enemy artillery can see.
If you have a good game but still lose you can come top on xp for both teams, I think winning team get 25% win bonus.
Artillery can also provide support by firing smoke etc... on the battlefield to hide friendly tanks.
The devs listen.
