Hm i really prefer Zephyr over SAG but i have no idea what item would fit to build out of Hunter`s Blade instead. I could also sale it and build Frozen but i guess thats too expensive and it also reduces your jungle speed again...will work on this. Thx for now and please tell me what you think about my idea.

I played shen with this build in a ranked game and i absolutely dominated so i thumbed this up, but i found a flaw with the item build.
getting the SAG (Soul of the Ancient Golem) as a core item with the zephyr is OK but its not getting its full advantage because the tenacity passive doesn't stack so i would recommend getting SAG with Wits End instead of the zephyr and making a separate route to getting a zephyr.

In my opinion the reason why you start with a buff is:
Blue:Better Clearing times
Red:Early gank
or what i also think is cause your team can help you with it easy and you will reach lvl 2 after killing what enables your second skill and as shen with the shield better durability in the jungle. So as i most times won`t skill Taunt as second skill for early ganks cause the lanes are not in a good position or something the red itself is wasted early but if i start blue and give it the the mid lane and thats something i really want to do cause it gives an important advatage to him i won`t reach lvl 2 if i start at the blue and thats connected with problems in the jungle. The second thing is when most junglers start at blue and your and the enemies blue have different respawn times it get a lot easier to save both for your team. Well thats just what i think but i never tried to start blue, give it to the mid and then continue jungling normally....have to try this i guess. Or did you tried that already?

This guide is quite good , from Shen player to another.
Just one thing though, I suggest you clean the first blue buff as soon as possible, should it be for you or your mid, because it will make the buff respawn sooner, and trust me, it is important.

The mastery description is wrong!Summoner's Wrath (Offense) also improves Ghost: increases the movement speed bonus by 35%!!
Thats the reason why i take it.

Dude, just noticed you have a point in Summoner's Wrath (Offense) but you run around Smite/Ghost. That's a wasted point.

That`s why i max it at last. I guess you misunderstood what i wrote, cause of my bad English :( What i mean is:
The only reason i would skill Taunt would be if the taunt duration would increase or the CD would get less but as with skilling it only the DMG increase i max it at last.

I like your guide its given me some insight, however I found a flaw you put, ranking up shadow dash doesn't increase the taunt duration. Just thought I'd let you know.
