I just tried creating a password since the upgrade, and also noticed this new limitation. "Two word pronounceable password will be extremely weak" is an assumption being made by Enpass, if users need a two word pronounceable password, that should be their choice (and assumption of risk).
Personally, I do need this feature. At the very least, there should be an option in settings to set the minimum number of words for pronounceable passwords with a default of "3"; this will let users tweak the generator to their needs.
