a bit short and unclear...

maybe check out this Your text to link here...

yes thank you i will look at your guide and with the dodge seals i try my seals with armor.
Ty for your help.

Maybe take a look at my guide? It's not the best but I managed to make it in top 10 and take a look at my items!

Ow yea and dodge seals, I don't know, you can better increase armor or a MrP (for little more dmg at start to harass and better farm)! You have 0% of your own so increasing that will only make it to 6.8% ... That's really low and a very low chance to dodge! You will only like dodge 2 times in the whole game ...

mh.. yes i see what your mean but i take for shen banshees veil, because of the magic resist and the spell blocker. It only blocks one spell but this is often enough for blocking a stun or when it comes good an ulti.

Ok i will sort it and write a bit longer.
What else for armor i can give Randuins?

What deathalo44 said is totaly true! It's kind of short and everything is kind of mixed together!

You should make different chapters for both champions or atleast make a title to make the difference!

Using Strenght of Spirit with Shen is stupid since he doesn't have mana! And why do you take Utility Master? You're not a jungle shen so you will only get baron buff in best case!

With tips and tricks you only have some for Leona!

You have alot of work on your guide! Ow yea, I would suggest adding optional items and explaining the choice more because stuff like Thornmail, are situational items! It is very good against an AD team but against AP, it's quite useless!

Its kinda short for a 'dual build' as well as the fact that it isn't exactly purely about tanks (Going throughout in every champ)

Note : Tanks are supposed to give buffs to teammates over taking it themselves. Increase buff times is not always that good. You can always put that point anywhere else.

PS : Shen has no mana. Mana/Mana-based masteries/items are not that good.
