I would like to see statistical phylogeneticists deal more knowledgeable with priors in such a way that we get better results. An entire tree is not really a single hypothesis.
Bremer support is fine.
That's a nicely parsimonious subclade. It is the fine structure of big trees, dealing with very similar taxa differing by simple characters that I question. They are not corroborated. Coincidence may be due to convergence among daughter lines. There is no independent test.
