You think people just get wriggles for the lifesteal and the free ward? How about when you're counterjungling and you kill their red buff in 2 seconds flat? It also helps you actually kill objectives. Also, the damage on executioners doesn't stack. If you hit them, and hit the 2 seconds later, you'll only get 8 damage from the 1st hit, not 32 damage. It doesn't do nearly as much damage as wits end, especially when you're dueling someone.

Shyvana is classified as a hyperganker/counterjungler. Strong level 2-3 ganks, but after that they're meh. The biggest goal of shyvanna is to counterjungle all day long, and you only have 4 sentences describing how to counterjungle, which saddens me.

Your items are a bit... meh, I recommend changing them to something more tanky. Mercury's Treads, Frozen Mallet and Wit's End are a fine first 3 items (along with Vampiric Scepter), but the other 3 can be more tanky. For example: Force of Nature, Sunfire Aegis, Atma's Impaler.
Madred's Bloodrazor and Ionic Spark are not that great items, while Executioner's Calling is only situational.

Tough Skin , Bladed Armor and Indomitable are really no good masteries, I recommend changing those points into Resistance and Vigor .

You could try to mention some alternative runes, and more alternative items.

Give some screenshots about where it's best to ward.

Also, give the reader some tips about what you do in team fights.

jhoijhoi is still a woman, afaik :D

An overall 6,3 it is, but your guide will need quite some improvement. Best of luck with that!

21-9-0 better masteries, also in your offense tree increased minion damage > flat AD....

item wise wit's end is 2nd tier, and getting ionic spark as a 6th item is terrible; a 3rd tier item at this stage of the game is going to leave you seriously lacking. madreds expensive and with only mallet your not going to be tanky enough

NICE build
