The latest change to combat in the last patch had the unfortunate effect of buffing TWF. I say unfortunate effect, here, because TWF characters are known to be far superior to THF and S&B characters which both lost DPS in this patch.
Previously at end game, TWF had twice more attacks per round than THF and both were attacking fairly similar attack rates. Now, both fighting styles' attack rates have been (supposedly) equalized. However, this means that TWF have received a straight buff to attack per minutes and therefore to DPS as well. Instead, it should have been THF that got improved in order to close the gap between the two fighting styles.
What I suggest is to change the two weapon fighting feats to behave this way:
- Off hand hook on animation #2.
- TWF adds off hand hook on animation #1.
- ITWF adds off hand hook on animation #3.
- GTWF adds off hand hook on animation #4.
- Ranger Tempest III adds main hand hook on animation #4.
The base hook to the fourth animation has been removed to restore the balance. The additional hook from GTWF on the first animation has been moved to the TWF feat in order make the feat more appealing at lower levels and to make TWF more competitive at lower levels where it lags behind in comparison to THF and S&B. It also helps making 11 BAB less of an important bench mark to a TWF character. Finally, the Tempest III hook has been moved to #4 to add further incentives to complete the chain.
This way, all TWF characters are returned to their pre-9.1 attack/round ratio (except Tempest IIIs which got a small buff).
