Yeah, it's basically super dumb because of stuff like this:
Foe-Seeker Ammunition Level 12+ Uncommon
This arrow creates a magical link between you and your enemies, making each of your shots more accurate than the last
until you strike home.
Lvl12 +3 500 gp Lvi 22 +5
Lvi 17 +4 2,600 gp Lvi 27 +6
Ammunition
Enhancement Bonus: Attack rolls and damage rolls
Property
13,000 gp
65,000 gp
When you make an attack using this ammunition, you gain a
+1 item bonus to the attack roll. If you miss, during your next
turn, choose another target within range of the original square
you attacked from and make the attack again as a minor action,
increasing the item bonus by 1. You can repeat the attack this
way each round (and increase the item bonus) until the attack
hits or until the end of the encounter.
I wasn't kidding when I said it was autohits forever.
