Primary vs secondary mod stat importance

Here is my KRU for example. I utilize Health Sets to synergize with his Leader and Unique abilities, and Two Health primaries as well as two Defense Primaries (and obvious speed triangle and offense square) . I have as high speed secondaries as possible, and I used one mod with strong Offense secondary to help with his Focused Rage special in which he also recovers health... otherwise I looked for as much health and defense as possible.

Hope this helps!
