Wonder how may players have accomplished this goal (probably less than a dozen). Just got mine a couple of days ago.
The hardest one for me is the Titan Destroyer, because I always play Titan first and rarely gets to play a second match without lost connection. Waited till win #740 to get that last one. Other players have fared better like Slaweck and KettleLid who both have completed 64.
Good luck in your pursuit. Post your name here if you have got it.
