Verbs become a bit tricky when they are heavily inflected, with the most common having the most irregularities. Collisions become a problem too, it's almost as if a heavily inflected language, with a fairly consistent root vocabulary, quickly runs out of distinct syllable combinations. E.g. Portuguese, and presumably the other romance languages. Compare the past perfect of 'to go' and 'to be' in Portuguese - they are identical for all persons.

Getting the wrong inflection ruins any sense you're trying to make!
