Have a few pretty recent quotes from the developers of WoT:
“Chinese TDs will be released exclusively for the Chinese server, in other regions THEY WILL NOT COME” © Anton Pankov, 6 March 2017.
“We will not introduce the Waffentrager auf E 100 back again. We are not looking forward to such a goal” © Daniel Parashchyna (Murazor) and Vyacheslav Makarov, communicating with the players in December 2016 at an exhibition in Moscow.
And now, we are seeing them doing the opposite. This shows that WG is not to be fully trusted, since they do not respect the promises made to the players in the past.
What happened to Wargaming, and most importantly, what happened to the respect for the players for which the game is developed? We will never know, but I fear no WG Fests or portal apologies can really solve this problem.
