Should Deathbringer Eliminate Clerics? (Patreon)

I'm seriously thinking of eliminating clerics altogether. Here's why: clerics are a unique D&D convention, invented by Dave Arneson, specifically for that game. They don't appear in myth or fiction prior to D&D and they don't really fit into the grim dark vibe of Deathbringer. They also come with baggage--everyone has their idea of what a cleric "should be," and any limitations from 5E seem like I'm nerfing them. They can also bring dead characters back to life, which I HATE. Plus, like elves and dwarves, I think they're a tired trope. 

My thought is to completely replace clerics with the Plague Doctor, which still uses WIS but uses science instead of spiritual healing. Plus they make bombs, which is cooler. 

Thoughts?
