OneD&D UA - THE CLERIC AND REVISED SPECIES

[Psyren]

If you are going to build for heavy armor, having to build for medium armor at level 1 (and only level 1) is bad design.

No, it isn't. You chose a class that doesn't start the game with heavy armor proficiency, so it's going to take longer than 1st level to get going with that concept. That's intended. It means that you are free to dump dex at level 1 like other heavy armor users would, but you will face a drawback of being slightly less protected at level 1 than they would be for doing so.

But it is not risible to point out that it is a problem.

I'm not laughing at anyone, I'm acknowledging that this is a nerf. But it appears to be an intended one. Clerics are not intended to be able to override their base proficiencies at first level anymore.

And hell, this could have been much worse - it could have still been tied to domain like it was before, meaning you'd have had to wait until 3 instead of 2.
