You're Offense mastery tree is a bit screwed up (least, it is on my screen). With the rank into the 15% magic pen, but no ranks in the CD mastery? Your runes could use some reworking. Such as i saw mentioned were armor pen marks, armor seals, and you could likely find better glyphs and quints. It would be good to add some colored texts to your guide, it makes it more appealing to the eyes than the same color over and over. I do, however, like your skill sequence. There are also some grammar mistakes (such as capitals and so on) but that's just annoying to me, i don't know about the general populace. And for a guide on a champion, you aren't reinforcing your ideas as much, just saying you use this and that, but other people can use whatever they want. People don't look at guides to be told that whatever they think is best will work, a lot of people don't know. Just saying that you could fine tune it a bit better, but regardless, +1.

The trinity force gives you enough attack speed, and since thats the item that you first rush, so attack speed runes aren't that important, but like i said, the runes should cater to your style of play.

You are right about how there are ton of trinity tank Irelia builds out there, but I feel like mine is fine tuned, and maximizes her potentials. I was kinda hoping for a crticism on the actual build.

I recommend getting armor pen reds, armor seals, mr glyphs, and some kind of defensive quints. Reasoning is you'll probably be getting harrassed alot while farming and those make you really durable. AD reds and quints are really only useful for last hitting but it wouldn't really matter if you get zoned for being squishy? Also since you have no armor pen for your auto attacks, why not get an attack speed item to synergize with hiten style?

hey, dont take it personally, just... why do you make build that is here already in 20 instances, just with switching some of the tank items? you cant get tank items according to build anyway and going irelia trinity + tank is so known that its most likely waste of time making a new build
