you've got to be kidding me. The issue...again is this:
Burn traps have the damage applied in such a way that the burn DoT does not have a chance to apply damage (because it is reset). Given that this trap does not disable enemies in any way, AND given that the PT cannot atatck while the EX trap is going off, this appears to be a a bug, or at least an oversight.
Several fixes have been proposed.
