Why do you punish players for building a team?

The scaling is what makes GW both a challenge and a training ground for new players. Both the scaling as you progress through the 12 nodes and the scaling as you develop your top team. You can complete it most days - but probably not every day. If it was much easier it wouldn't be the same training ground.

Once you reach the cap (or get to sim at level 85 - 50 completions) GW becomes too easy, boring and uninteresting.
