War Thunder is RIFE with flaws and intentional changes to tanks to make certain nations more powerful than they were in WWII.  The Devs are all RUSSIAN, gee I wonder which nation is the most powerful.  Add in that the RABID FANBOYS will defend to the death that this never happens and cheating never happens they will BAN and CENSOR any person that posts on the WT forums.  I gave up on the game three years ago when the bias and PAY TO WIN became so blatant.
