Especially since it was a highlight that Rockets got buffed...even Exotics
If the nerf is intentional, it would be very welcome and helpful for the community to hear the rationale behind such changes. I'm certain the team is well aware that the community thinks exclusive raid exotic heavy weapons should be powerful, and this is not the direction of change people wanted. Better to address this up front.
Just confirmed that any damage reductions were definitely not intentional and the team is currently investigating it as a bug.
Adaptive Ordinance only triggering off of kills is intentional as referenced in it's description.
