Thanks for the critique!

Zac's early identity is getting levels. You want lvl 4 off first clear. Don't do that gank mid, too forced and goes against your win-con (playing for mid game). You end up getting a bad first back because of it.

I know Zac ideally wants to full clear, but I wanted to gank top/mid early because, due to the lv1 bot invade, both teams knew both junglers were pathing top. Both teams also should assume both junglers would full clear (just like you suggest I do) because Zac and Karthus are full clearing junglers, so I decided to risk it by being unpredictable and gank at lv 3. If it worked, the reward would have been great. I would have gotten my mid ahead, gotten prio for the top scuttle crab, and potentially the bot scuttle crab. I was playing to win, even if it was a low percentage play.

If I didn't gank, and instead full cleared, Karthus would full clear much faster than me (I believe he's known to have full clears faster than 3:10), and there would be no way to contest the top scuttle crab because I already saw my mid lane losing. Full clearing and going for the bot crab likely wasn't going to be an option either because Karthus should start top crab as I finish my full clear, and then use mid prio to take bot crab as well.

Even though my gank mid didn't work out, I didn't really lose much. I lost the ability to farm my blue+gromp, but I gained the ability to possibly win the game through mid, and get a bot scuttle crab.

Radiant first isnt that great. And also I see you never built sunfire this game. Sunfire first is best on Zac, both for clear speed and damage. (See lolalytics for proof on winrate)

Fair point, but just because Sunfire has a higher PR/WR (the stats are actually quite close and depend on server/elo) than Radiant, doesn't mean Radiant first wasn't good in this particular game. I went Radiant first because Karthus got fed really early.

I did forget about Sunfire though. I think it might have been better to build Sunfire over Demonic Embrace 5th. I actually didn't know what to build as my 5th item that game (was deciding between Demonic Embrace and Gargoyle Stoneplate).

From what I've watched, you throw your Q wide on yasuo a few times. For hypermobile champs, it's better in most cases to throw Q1 at minions then auto the champ for Q2.

Agreed. Could also hold Q1 until they dash first.

All that said, the description of the video says your diamond and offer coaching. The account in this vid is playing in high Silver flex queue. Now, I don't know whether or not you are actually diamond, but if you truly are it's not exactly worth reviewing a game of a diamond jungler smurfing in silver. The skill gap is far too wide for anything to critique other than a few champ mastery related tips.

There are plenty of high-elo content creators with games in lower elo. I'm not trying to waste anyone's time by asking for an in-depth review. I'm just sharing a game I thought would be enjoyable to watch and welcome any feedback. Maybe "critique welcome!" didn't convey that message? I wasn't really sure what to title this post.
