I've asked this before as part of other questions, but how can I find out which characters are strong or weak against any others? Or which characters are stronger magic or physical? I haven't found any reference to where that would be, only that I need to when I lose.
I've looked at stats but nothing is obvious. There are some physical damagers with more intelligence and some magic with less intelligence.
And as to the colosseum, that's a lot of trial and error, but a lot of factors go into any given fight (including the defensive AI, which seems to be much better than the offensive... I've faced identical teams at lower levels that won in a landslide)... suggesting the colosseum is a total cop- out answer that doesn't really answer my question.
