For a four star tanks the Mk X is a nice cheap evasive, but it's saddled with a terrible active skill. That 152... It's just a SU-152 with a bit more health a mild damage boost to it's active, but also loses evasion? The SU-152 already costs too much for being an underwhelming jack of all trades. Yeah, not seeing how this one qualifies as a five star tank. Oh well, she's got nice art and she can scout.
