They are not going to listen to your complaints or do anything to fix the game.

Save your time and request for refunds and exit the game at your wish!

Just quit like I did. This is plarium who you're talking to.

Hello! The Mech remains to be relevant and effective within its Rare Grade. You're welcome to use appropriate Implants and equip it with some Mods to improve your game experience and make your Tengu more effective and compatible.

Tengu is good, just not at end game matches

Oh I see so you are saying I am more than welcomed to pay more for the game? That sounds reasonable, if someone is that dumb. I mean cmon, are you serious? You downgraded Tengu after you made people buy it. How is that fair, give him back its original stats. 

I don't think you are being reasonable after purposely downgrading something we purchased

Hello! The aim of the rebalance was to make the Mech meet its Grade and Class as it helps us keep the game balanced. Nevertheless, the changes are not that dramatic - we'd recommend giving it a try and maybe testing some various strategies and tactics. Tengu definitely remains efficient and relevant within its Grade and moreover, the Mods may make this Rare Mech even a more dangerous disaster on the battlefield!
