Mastery Page Text (small bug)

A couple mastery descriptions have their text run almost out of the box on the right side, leading to a slight difficulty in reading.

This happens to me on :

Phasewalker (the word 'Enhanced' runs off the box and is thus cut off.)
Summoner's Insight (the '%' sign)
Dangerous Game (the word 'and')
Frenzy (the word 'seconds')
Arcane Blade (the word 'equal'. the 'l' can't be seen at all.)

I don't know if the box isn't large enough or of the text missed going to a new line. Perhaps centering is the problem.
