BH Duty's gift talent proc on elite

BH Saltzpyre’s Duty’s GIft talent only procs on elite kill, however it doesn’t proc on special kill. Isn’t this a weird thing to make exclusive to elite, but not include specials? Normally these types of ‘on special/elite kill’ talents are either specials only, or inclusive of both.

Talent says: “Killing an elite while out of ammunition restores 30% of max ammunition.”
It’s exclusively elites.

I’m not sure why it shouldn’t include specials, it would open up more situations of the talent being useful and would still remain balanced because of the 0 ammunition requirement.
