Tactical DC while leveling is problematic.
If you dont use Stunning / Trip weapons its really hard to hit the DC required and the only other option to increase it is via Cannith Belt (no other that i know of) and while the belt is really great at epic its underwhelming while leveling.

So i would like to see
1) new Red Augs, Stunning/Trip/etc
2) Blue slot on Heroic Cannith Belt
3) more items that give exceptional DC
4) new items that give DC and are not weapons (in epic we have a few armor but in heroic nothing)
