Maps are Dragonshire and Blackheart, and you're planning to fight for the objectives and not the lanes or the camps.

Enemy has a diving strategy, or no strategy but they have two assassins or more and they're going to be gankers.

This is the best build to get when YOU KNOW they will be coming for you. Those gankers type: Zeratul, Muradin, Illidan, Nova, Kerrigan, Falstad players, cocky and ignorant, to gank a Valla trying to get her objective as if she was an easy pick off.

They got another thing coming. More like 3 hungering arrows up their ***es.

Pros: Anti ganker. Good sustain to heal and absorb talent magical damage. Highly mobile with 2 Vaults and bolt.
Cons: Enemy creeps hinder your damage output, skill shot may miss, very mana hungry.

Power spikes: As long as you are 1v1 with NO CREEPS near, you've got the advantage.

Level 7: At only 1320 HP, fire 2 Hungering Arrows for total of 855 single target damage and 427 heal for Valla. With a few basic attacks, most assassins die or flee.

Biggest power spike: Level 16. A mana hungry combo that uses 3 hungering arrows and 2 tumbles for a total of 765*3 single target damage (2295), and 1147 heal for Valla. Also, Spell shield (50% redux to ability dmg).
