It shows that you know what you're doing. Its a good sign though. You are able to take feedback and discuss it. Its shows that you arent so arrogant in your build, and that you are open to ideas

Yes, I have considered getting those for the last item. There may be other items that are a better possibilty. On the other hand I don't know if it's needed to put a last item. (I will just to be safe) But, I rarely ever get to get more then this build has shown. Just cuase the fact of all the items I chosen for my build cost alot. And, not many people are able to get the 6th item.

I probly won't get the Rylia's Crystal Scepter cuase I already have a slow effect item (Frozen Mallet). It'd be nice for the HP and AP, Yes. But, The Trinity force would have much more effect and doesn't cost a whole lot more. I'm trying not to make this a AP build. It'd be more a "Hybrid Build". But, I like to keep my hp at atleast 3k end-game, Have a decent amount of physical dps, and Guinsoo's Rageblade mainly 'cuase it works when you switch through stances. Allowing your passive ability to activate and Rageblade to gain stacks with your passive. (Passive gives more Attack Speed everytime you switch through stances.) Which turns out to be a significant difference. So, Thanks for the pointer. I will most likely put Trinity Force in there. Rylia's Staff is not exactly "My type" of play. I will test it out to see if the slow effect stacks with Frozen Mallet. Thank you for your comment and suggestion. Helps alot.

(How does your short paragraph turn to me writing a huge one...?) xD

I like this in terms of DPS. Im not a Jungler, but I am a Bulky DPS.

I think that this is a great build. I mean is a great item since you are playing a more AP build. Since you are playing AP, have you considered rylia's crystal scepter or as that last item? They work great with Udyr
