I translated "Omväxling förnöjer" which basically means that variety makes things fun/interesting. Google Translate translates it into "Flip a switch". Translating each word alone gives me "Variety" (Omväxling) and "Spice of life" (Förnöjer). Well, that was a little off topic.. What I really wanted to do, was ask what kind of change you've made to a character to make it interesting again after it's lost some "color".
I tend to head to the tailor.
Example:
First Jax
Second Jax
Third Jax
