After a few years of playing I finally got tier 10 vehicles in every class in all three games. Ironically, WoT was the last to complete this because of the recent addition of tier 10 Light Tanks. Despite the occasional grind it has been quite a fun journey, thanks WG for making these games!
While it is not a difficult feat to accomplish (I am just an average player) I have not seen many players who have done it. Give me a shout if you have.
Here are the screenshots of the tanks, planes and ships.
