You DID say three posts earlier...
... so yes. Not only do I (a stranger to the conversation) think they would change a class so drastically, but apparently TURBINE thinks they would change a class so drastically, and since you quoted them you believe they would change a class very drastically as well. I'd call it a drastic change to take a class that can do a lot, and "update" it to where it can't do everything. I think that making a tank less of a tank is NOT as drastic as taking a class that can almost do everything and reducing it to where you need a party to replace it.
