Simple solution to Zed/LeBlanc/Fizz etc
None of these champions are OP as such, so simply reducing their numbers would force them out of viability, equally completely reworking them would potentially ruin fun champions who do add to the appeal of LCS with their flashy style of play
So
Release a support champion based on keeping the carries alive, something which hard counters them. Say maybe give them an ability which allows you to cleanse one of your allies, so the assassin really does have a decision to make based on baiting a carry away from their supp or trying to bait out the cleanse. I think this would be the most healthy and most strategic way of balancing these champions so the next time some firstpick hot shot thinks he will carry with LeBlanc, your lastpick thinks 'not on my watch sonny'
