My buddy ExecutionerJDog has vaulted from tier 2 to the top tier long before he was prepared for the action there. I see it happen all the time. Someone rolls through tier 2, and within a few weeks, they are in the top tier because they upgraded the wrong robot too many times. There are ways to go back. They are covered in other videos. These people tend to invite my tier 2 account because that's the account they know. It is really difficult to last very long, and my tier 2 weapons don't do a lot of damage to the big robots at the top, but I help out how I can.
