I picked up this tank in order to complete the Czech portion of the Czech Holiday missions as the female crew you can earn would allow me to crew the Skoda T50 (a great tank that has been crewless in my garage for a long time).
Overall, the Skoda T 27 is a good tank. Not a must have; it isn't OP and doesn't bring any new features or gameplay. Nobody is going to rage against its addition to the game...which I think is a good thing. Playstyle is very similar to the tech tree Czech IX and X tanks, and the crew layout is also the same. If you like those tanks, which are fun and competitive
