Please fix Kennen's early game, so he's actually playable in this burst meta
His entire combo is basically only useful during laning as a disengagement tool; it doesn't have anywhere near enough damage to score a kill, unless your opponent is staying in lane with 30% health. Which often isn't useful against assassins, because most can kill you through your ult.
This is really problematic when games are over in the first 10 minutes. In order to be viable, champions need to have kill potential or be able to punish mistakes during laning, which Kennen cannot do.
