Very well done on this! Think Scatter might finally become a used talent. I'll certainly level my ninja and AC now, and give me something to spend my gems on, since all my other heroes now have something good at 4/5 or 5/5.
Not sure how effective scatter will be - it can't stop something proccing, since each hit will only lower energy by 10 (-25 from scatter, +15 from hit). It will certainly slow down, and could stop the proc against slower attack spd target such as Mino/Cupid, or when used by GR.
Deadly strike could be a very good talent also... It effectively adds 70% damage at 5/5, but cannot be relied upon to proc with any consistent regularity. Also, self destruct.... What happens if a hero dies, and kills the other? Be interested to find out.
