Rip crit halberd?

Personally? DT is pretty situational, one of its main attraction is its ability to 100% Physical Pierce. Which means it deals the same damage no matter how high the target defense is, so it should be much more effective than SS on high defense boss.
The second attraction, is the reason why he ask the question: its ability to crits no matter what. This means we can switch the crit rate stats for something else that might increase the damage output (STR7% ATK7% CritDamage 7% on both armor and halberd??)

 

This is true, and also elem/stronger against elem might be feasible for halberd now. I havent tested it though.
