Watching your youtube videos, and i love that your trying to help people. Very few people do so i think your great for doing it ill probably watch your stream too. Just a few things that id like to point out that i believe your missing in your teaching. Your videos are great im already learning from them :) keep up the good work ^_^
First in your xin silver 2 video, when he did crab top side it actually is giving your top lane a false sense of security. The reason for that is because if gnar were to come from blue buff you can hug the wall and that crab will not actually have vision of you, so you can still gank top even with crab ward. The only reason in my opinion to do crab is if your trying to heal, or if you plan on making a play around that area. Instead of giving top a false sense of security.
I see that the xin doesnt go red trinket which is a lot better then yellow, because yes yellow trinket does give a ward however hes a jungler. He needs that red trinket to clear wards in lanes so that he can actually gank those lanes. You can clear a ward then pretend your leaving, but still stay in the bush and wait for him to come back up. Also it helps greatly when doing dragon/baron. Later in the game when you want to do baron having 2 red trinkets will help even greater with that. The support can trinket around it first then if they place a ward in it the jungler can simply trinket it, and not attack the ward which will cancel the vision. Same thing for dragon plays.
When he put the miss placed ward in dragon pit, i saw that you didnt correct him on another mistake besides just the ward placement. Bot lane and mid were both missing, that was a super easy dragon, and with xin having dev jungle item its even more important that he should go for that dragon. Zed was also not there however the bot lane was, so that was an easy dragon that was just missed.
I dont really feel that going dev is a good item for a jungler, because of the fact your spending 2k gold so you can wait to use your item. Its like spending 60$ on a game then have to wait a week to use it. Now with the item being nerfed makes it even more bad. The ad item brings so much more dmg early and early game is when junglers matter the most. Also when you go back and buy, the xin had it his first b, but you wont always have that and when you go b 2 long swords is so much better then 2 daggers.
He bought mobil boots which isnt a good idea in my opinion, because of the fact that xin is a front line champ hes a super easy target to cc and merc boots would help so much more in that. Also they have double ap mid/top and they have sona which does a decent amount of ap dmg, depending on the build that the sona goes, so the merc treads not only reduce the cc which he as a front line is almost certain to get but also give him better defense. His bot lane is basically a troll bot and they have next to no cs so bot lane is probably not going to be focused any time soon, so that makes xin even more of a target to go on.
I dont think xin should be even thinking about bot lane unless dragon is up. They have basically no cs, no kills, xin isnt fed, even a 2v3 there is next to no chance of winning that unless the other bot messes up badly. He should be trying to snowball zed mainly in my opinion. Rek isnt a bad champ but hes not usually a snowball type. Veigar is easy to gank and zed and xin are both good snowballing champs.
On some of his camps xin tends to keep hitting the creatures even though it has next to no health and will die on its own even when he has red buff. Trying to focus on as few hits as possible will make his clear faster, which will give him more farm and more chances to gank.
I think your doing a great job :) i hope to see more videos in the future to learn from you myself ^_^ i would love for you to teach me as well if you have the time. I dont currently have a replay so ill need to play a game and get one for you. I do have skype
If im wrong with any of the stuff ive said please do tell me why i am
