Cost 7 is never justified.
I have hard time already justifying using my two other 6 cost 5* HT. Very hard to find use for the 6 cost TD that was recently in blueprints shop. She almost never gets deployed onto the battlefield unless I already have a good death ball rolling.

I did grab the current MT 5* as I saved my blueprints from the event, not using them on Eliting Edna nor Minnie. Would like either some good artillery or Light tank next, but with the PoC being shut down, the blueprint income has been gimped drastically so I wouldnt be able to get enough in a one week anyway.

Any1 took a look why they dissabled it ?
