No Kennen changes?

Mark of the Storm (Passive) diminishing return timer lowered to 6 seconds from 7 seconds. Thundering Shuriken (Q) energy cost lowered to 60/55/50/45/40 from 65/60/55/50/45 Electrical Surge (W) energy cost lowered to 40 at all ranks from 45. Slicing Maelstrom (R): Duration now 3 seconds at all ranks from 3/4/5 Now does damage to all nearby champions every .5 seconds from random nearby champion every 0.25 seconds. Additional hits deal 25% less damage (to a minimum of 50%)

Cheaper abilities and the ult does more damage to ALL enemies in it instead of random players but at a longer cost. Making his ult more reliable if well set up.
