For the moment consensus is good because some people aren't totally sold yet, when people decide to vote seriously at the EU elections, when they truely own the project then we can vote at the qualified majority.
I mean currently you have people who are pretending that the EU is a dictatorship where the UK can't make its voice heard, so imagine the shitstorm if it was actually the case.
Also I believe that the qualified majority needs to represent at the same time: 70% of expressed suffrages, 70% of funding, 70% of population. Obviously the figures can be adjusted.
