Well, St. Teresa was called before the Inquisition. Does that count? The political climate when St. Francis was active was AT LEAST as toxic as when Luther was. St. Catherine was active during the so-called Babylonian Captivity, when the papacy was at Avignon--so, worse than what Luther was facing. Leo the Great faced, among a great many other things, the invasion of Attila. Gregory the Great was contending with the immediate aftermath of the fall of the Roman Empire in the west and constant barbarian invasions, a plague, etc. Luther was writing in an academic backwater.
By all means, make the case that the climate Luther faced was especially bad. For my part, I find it very difficult to see how anyone could make that case. But maybe I'm overlooking something.

This reply was written to your pre-edited post (quoted in full above). If you'd like to know what they reformed, a Wikipedia search will likely get you started. And I'm not sure what you mean by "obstructionist". I'll need you to say a little more about that in order to respond in a useful way.
