Is there any specific reason as to why I should be using only brutus? Playing with trickster hasn't been half bad, how is playing with brutus better for me?

I have a LVL-11 brutus drone, but i also have LVL-3 trickster and booster. Assuming I usually play with firebird+viking, which would be the better drone to use?

Fix the matchmaking so that a First Sergeant with 1.5k gear score doesnt have to go against a Captain with 7k gear score and a crisis drone

You can download the non-steam game client at https://tankionline.com by pressing the download button. This client will allow you to log into your account instead of using a steam account. The changes arent that drastic but if you're running a single-monitor setup it might benefit you to download the client so you can alt-tab to youtube if you have music playing or something.
