And here is my justification:
I am a damage dealer, and DB fits well with my supreme cannon and shotgun, as well as Clash. It deals good damage, shreds resistance (like clash, shotgun and SC) and gives OK-ish heating. BUT if you are true heater, you will want to stick to Corrupt Lights. You need to combine them with some push (Abomination? rare as hell) or repulser, plus Heat Nova (Reckless beam?) and a proper drone (Murmur or Nemo). This is the setups you need to go into. So whatever you max is based what else you mounted on your heater.
