Simply put, with the coming of 1.6, strength has became way to overpowered and is removing the balance in AoD.
Strength 1: 130 Percent Damage Increase
Strength II: 260 Percent Damage increase
To try and put this into some perspective, I'll give you a few items and their damage after having Strength II applied to them. (Note: This doesn't even include critical hits, which already double the damage on a sword)
Regular Diamond Swords do 7 damage ( 3 and a half hearts)
With the edition of Strength II they do 18.2 damage ( about 9.1 hearts a hit)
A Sharp V Diamond Sword does from 6-12 hearts of damage.
Meaning more than 50% percent of the time a regular Diamond sword with Strength II will do more damage than a sharp V diamond sword.
