This is a good 3v3 build for ashe. 5v5 may be a little different give it a try. As far as im concerned about runes. do what you gotta do. What ever makes you happy, then im happy. This build is excellent for solo laning long into mid game. and in team fights you will be unstopable. I have had success in this build. I usually take ashe solo up top and jsut harrass the other champion until level 6, then i become more aggressive in both lane and ganking. Right around level 11 I can usually take ashe and jungle. Ashe is squishy for me and I notice champions focus me more, so I use ghost and exhaust primarily for escapes when I solo just in case my health or mana is low. make sure you solo in the beginning. this item build is very expensive! I have debated putting some points in hawkshot first to get gold with every kill. But philosophers stone usually helps with gold. Also manamune is very helpful if you are in a heavy tank game. I have not tried this build in 5v5 so be careful. If you are getting focuses a lot go with some healht and armor. Being a support DPS is better then feeding!!!!!!!!!
