ARE a must to empower:
aimed shot = max DMG/CD
power shot = max DMG/CD
nature's mist = max CD
Piercing shot = max CD
alternate (really depend on you if you want to empower)
Multi shot = max DMG/CD
you will still have reserved points for future archer skills
my build is 25 SPR/all STR (bow user, dunno why

)
For PvP:
Well, how could i comment on this.

Archers can only kill fellow archers and mages. No chance for fighters at same level or -10 lvls (and for those who said they can, dont kid yourself). Impractical to kill clerics. Kiting is your only strategy. Prepare to be called a coward coz they WILL call you that eventually.
