Could we make some of Katarina's damage a little less easily confirmed?
While I recognize I am still a scrub at this game, I feel that for the amount of damage Katarina can dish out a lot of it is far too easily confirmable, especially against melee opponents who have to always be in her effective ranges whilst laning.
Three of her abilities will always hit the target(s), with two of them having no real counterplay to stop them (Bouncing Blades and Shunpo) other than "stay out of range". Her only skill that isn't "unavoidable" is Sinister Steel, which is pretty much a near instant melee-range (a little farther tbh) ability that Katarina can activate immediately after using Shunpo, practically guaranteeing her the hit.
I just think something needs to be done to one of her abilities (perhaps Bouncing Blade or Shunpo) to make Katarina a little more "skillfull" whilst giving opponents more actual ways to avoid her damage or counter her (outside of CC'ing or getting out of range during her ult.)
I don't think her damage is necessarily the problem (most assassins have just as much, if not more damage) but the fact that a good bit of it is unavoidable.
