You don't have to play against/ with super heavies, D-Weapons, Escalation (and so on), if you do not want to. It is the choice of each player whether he or she wants to set up against an opponent using these models and rules.
As Grimwulfe said, people have chosen their camps (yay, nay, or indifferent)...if you don't like D-Weapons don't play games where they are in use, don't go to events that have them.
We know they change the game. We know they are powerful.
Why continue the debate?
The tournament community and vast amount of TOs will decide what they want to include, house rule what they think is best, and go from there. It will all get sorted.
