Kled change proposal
I'm sure we've all played against a kled. Many of us in the jungle or toplane have probably experienced the frustration of being unable to quite finish him off due to his remount mechanic - especially frustrating if you dismount him twice only to have him remount and thus outsustain you or survive an all-in. My suggestion is that kled remount have a cooldown - a decently long one - similar to zac or old aatrox revive passive though perhaps a bit shorter cd than that. This would give players a better chance to punish kled for overstaying with no backup if he is dismounted and has already remounted once.
At the same time, and in compensation, I would suggest making kled w (3 hit) an active so that kled players could use it when they wanted - like when trading with an enemy toplaner instead of having it activate "randomly" when they are trying to last-hit under tower or something where it can screw up farming or just be wasted on minions instead of bullying enemy toplaners.
I believe both these changes enacted together would introduce more playmaking and counterplay for both kled and his opponents - allowing players to showcase their skill more than the current kit does.
