This guy already has one of the strongest early games, has a gap closer which goes halfway between turrets, and probably the best level 2 ganker in game.
He doesn't fall off late game despite a stellar early game and causes the entire jungle meta to warp around him and an incredibly small pool of early game gankers while strong. What the fuck is the balance team at Riot smoking while buffing an already viable champion?
For those not aware, the buff is a slight cooldown reduction of Three Talon Strike from 9/8/7/6/5 to 7/6.5/6/5.5/5.
I would like to point out this is largely a midgame buff only.
Xin Zhao clears just fine, often only needing one usage of his Q per camp if that, and the cooldown doesn't typically carry over onto other camps. Furthermore, this change does virtually nothing for early game ganks. I suppose this may help out in 1v1 fights in the early game, but you shouldn't be 1v1 fighting Xin Zhao in the first place so no effective change there.
On the other hand, as a buff only to his early rank cooldowns, it would effectively have no difference by late game.
The real change I think this may cause is that it would give more credence to E Max second Xin Zhaos, since there's even less marginal gain per ranking his Q.
To respond to the OP with this in mind, I genuinely don't think the problem is buffing an already strong champion necessarily. The real problem as I see it is that it may emphasize a strength of Xin Zhao that people already hate, that being that if you get caught by a Xin Zhao (especially an E max second Xin Zhao), you're already caught and you're probably already dead.
Xin falls off pretty hard.
Cause they don't want to nerf 
etc early strong champions so they got to buff others, that is their logic and you can see it in many other things where they buff one thing to be op like other instead of nerfing others
The scuttle appears later, which favours level 3 junglers
It's a very small compensation buff
Same question on why Cait getting buffed.
"He doesn't fall off late game" Bullshit.
People are sick of the level 2 gankers yet Riot is buffing one of the best level 2 gankers.
????????????????
hey OP you know what im thinking.... https://youtu.be/q5mLjKI968g
strongest lvl 2 gank tho 
600 range targetted dash is now considered half a lane?
Nice hyperbole.
I love playing an assassin midlane only to get cheesed by a fleet foot xin zhao stacking doran's blades. Now it's going to be even more "enjoyable". The guy literally kills you in a single knock up and has a metric ton of self healing to boot.
You're saying Xin Zhao doesn't fall off? What the hell.
try him, doesnt feel that great tbh, apart from being able to pull off good lvl 2 ganks theres not much he brings to the table, his damage feels pathetic compared to other champions, same to survivabilty he can be good in an competetive enviremont because of his ult but thats pretty much it plus the only reason his lvl 2 ganks work in the first place is because people are too dumb to ward and afk under their turret during the first 1:30 min of the game
probably because he isn't very good right now
Same reason why Brand is getting a buff. The riot balance team is utterly useless and stupid.
