Rockets:
 * Cooldown reduced to 10 seconds from 20 seconds at all ranks.
 * Fires 3 rockets at all levels.
 * Rockets now hit the 3 nearest enemy minions or champions, instead of just champions.
 * Ability power ratio reduced to 0.55 from 0.8 to accomodate the significant cooldown reduction.
 * Base damage reduced to 85/135/185/235/285 from 90/150/210/270/330.

As you can see, with the reduction of cooldown the rockets had a heavy decrease in ratio, but base damage was not reduced accordingly. Just doing the opposite would have improved his gameplay, in may opinion
