Secret Trick for HP Bloat in D&D 5E

Here's a quick trick for making hit point bloat evaporate while still sticking "within the scope of the rules" for D&D 5E: just give the non-essential monsters the minimum allowable hit points for their hit dice. A monster with 12D8+36 HD might default to 90 HP, but in that range it could easily just have 48 hit points. 

This idea occurred to me recently when I was mulling over the hit point issue, and I have since tested it out a couple times....the results were quite satisfactory, and led to a more expedient combat where the "meat" of the encounter was not really about a prolonged mechanically drawn out fight. I will be using this lovely little hack more often, I think.
