Every time CertainlyT makes a champion I cringe for this reason except for the first one because at this point I don't even want to see what he's working on next. I still don't own, nor will I ever own Yasuo or Kalista because I feel that they will never be champions to me until their toxic kits have been reworked from the ground up.
I'd still not own Ekko, but I believe Gypsylord actually has a degree of humility and a certain level of sympathy for those who have to play against the kits he designs, and will adjust his champions if they're too strong. He's taking his time with Ekko though...he still needs looked at quite a bit. (3 slows, a big-ass shield, an execute, a speedup, a blink, an "oops" button that heals him and does more damage than Vieg in an AoE on an ASSASSIN? Really??)
New champion releases like Bard's are great for an introduction to the roster because they arrive border-line useless and might as well count for the sixth member of the enemy team. That's good! Now they can be buffed just enough that they don't get pushed over the edge of balance, while still being strong enough to benefit the team they're on.
