Sadly that was theorised years ago
By following the current course of real-life events,Gaijin made Top Tier basically “ops! It’s all Leopard 2s”
Realistically speaking the Leopard 2 is one of the most exported tanks in the world,so logically i get that many nations in the game would eventually have it.
But still,this further points out the reason why we better needed a Pan-Continental Tree,just like a known ship game: European TT with all minor nations (BeNeLux,Hungary,Romania,Poland,Greece,Spain, Switzerland,Austria,Denmark and so on), Pan-Asian TT (Thailand,Indonesia,Middle-Eastern countries,India,Bangladesh,Pakistan) and Commonwealth (Canada,New ZealandAustralia and South Africa)
Access to the European TT would be granted when you reached Tier V with a German,French,British, Italian,Swedish or Russian vehicle, Pan-Asian with a Tier V Chinese or Japanese vehicle and Commonwealth with British or American vehicle
So,as you can see,no nation is excluded (except Israel,but that’s because Israel already works like this) to gain individual access to another unique tree and Gaijin has the freedom of being creative with the vehicles and whatnot.
Without this remodel,i’ll only say these few words: just wait a few years until the F-35 will soon come,and you’ll see how extremely stale the Top Tier experience would be (7 Nations currently have access to it)
