If you're with me so far, we've gotten rid of Boosters, AND we've reduced the effects of Bats & Bots.
Guess what? we don't need Uber weapons anymore. Let's face it, ask ANY veteran player out there what weapons they mount and there's really only two choices for primary weapons - the "Uber-Guns" = PPCs and Coali gatlings.
There's a TON of really cool class 9 weapons out there that go totally un-used because the Uber-guns are so much better.
Sure, they are expensive and hard to get, but again, getting enough money is only a matter of time and every veteran player has enough time and money to get them, so everyone uses them.
Wouldn't it be more interesting if you went into a PVP not knowing for sure what kind of primary weaps your opponent would have? Some may have slow firing heavy hitters while others might choose high rate of fire gatling-type weapons. Right now this doesn't happen. I bet that 9 out of 10, if not all 10 of the players you face will mount one of the two Uber-guns.
Get rid of them...since everyone doesn't have Boosters, you don't NEED Uber-Guns to PVP anymore.
