This is my first guide, (Still in progress)
PROS of AA build

-DPS is smooth, as long as you keep shooting
-Dakka
-Your sustain is unparalleled
-It's good in 1v1s, duels

CONS of AA build

- Relies on Inspire, Berserk to gain massive DPS which has longer cooldowns
-Slow creep clears
- Relies too much on positioning
- less dps means someone is already on your *** hitting you in melee
- it's ****
- Searing Attacks is RIP
- Less survivalbility (unless you pick Give Me Moar)
- Seriously, just ****ing play Valla

Anyways, I see no reason to go for this build anymore because you no longer have anything reliable enough to augment your AAs and besides with the Doomguy build you get more CC.

Give

PROS
-High burst dps
-You can double tap a **********er and feel good about it
-Better bonuses (1 second stun and 50% vulnerability if spec bullseye, or 50% damage if you spec the other one)
-Better crowd control
-Doesn't rely too much on positioning
-Better creep clears
-You are more likely going to survive dives from Warrior classes
CONS
-Skillshot reliant
-Mana
-Your life will be difficult pre-level 13

Early in the game, I like to get exp as much as possible so what I do is mount up try to line up a perfect shot with piercing round vs enemy creep wave early on. However, this might leave you vulnerable to ganks from other lanes. So be careful in the early game. (to be continued)
