R/Ele - Shock Sniper Help

I have been reviewing the basic shock sniper build of a ranger. Here it as as I know it:

Expertise 10, +3 Rune, +1 Hat
Marksmanship 11, +1 Rune
Beastmastery 1, +1 Rune
Air Magic 10

Penetrating Attack
Hunter's Shot
Punishing Shot
Pin Down
Read the Wind
Favorable Winds
Tiger's Fury
Conjure Lightning


Whats the use of putting points into beastmastery in this build?

tigers fury is under beast mastery, although i dont think 2 points will do much

4 is enough for tiger's fury (3+1)

or you could raise it more for fertile season if u wanted, and tf would get better as well

It's to crank up the duration on Tiger's Fury, which has recieved a nerf since that build was posted.

Peace,

2 points and 1 attribute point. It's better than nothing.
