Is there a way to design end game content that doesn't lead to a caustic community?

Yes and it's by doing what SE is going to do come 2.2, they are going to make older content more accessible while rolling over difficulty into the new content. This is what works and hope to god they don't change it. The community loses the tension during these patch times only to rise again before patches roll out. SE already said that to remedy this they'll release major patches every 3 months until they finish expansions which will most likely be on a 9-12 month period.
