I wonder about the engineer tier 4 speciality card explosives expert. So far I only discovered one card it interacts with, D-Charges, and only with one of it’s modes. Grenades from the loot deck don't target enemies or seem not to involve rolling at all (so there is no need for adding). Upgradeable Weapons lack the needed Keywords (Explosive or Grenade). D-Charges seem to be Trishas signature thing. But still I think explosives expert is very weak, given that it is a tier 4 speciality. Ignoring that the effect itself is not so great, but that's more because of my personal taste, I think. Do I miss something?
