why did u put spirit visage?!

Confused with item lineup why two boots, then no explination in item section.
I do late boots with my style but these boots are later again and i feel that they may be way to late especially for early mobility and gangs.

Might be worth splitting up the Tiamat, instead of getting all the items and upgrading to tiamat get the Long Sword or Rejuvenation Bead and maybe the Pickaxe before completeing Mobility Boots then complete the Tiamat. This will allow you damage and mobility while still allowing you to get what seems to be your main item.

The Spirit Visage is an interesting choice and will work well with spray and prey however you will get substantually more healing from adding a Bloodthirster but i shall give it a shot. I understand that you do require this though as your build has 0 defenses by runes or masteries. The need for this item could be countered by masteries. I would get rid of Brute Force and add that into Sunder as i dont see the benefit of 3 damage compared to 6 less armor. and change the utility tree to defensive tree. Alternatively you will have to break up your runes to get rid of the need for spirit visage.

Finally might want to add some icons and pictures/colors into your guide as it is hard to focus on it without any breaks. There are some good hinters on this page on building guides and i recommend reading one and updating this one.
