Hey. I support using 5e stats. I'm one of the guys saying it. However, I'm not opposed to creating new monsters. However, the whole game shouldn't be new monsters. It should be mostly standard monsters with standard stats. Don't call it a goblin and then make it an orc. Either let me fight proper orcs or proper goblins. Don't give it a goblin skin but orc stats. That's my point.

Make a new monster? Give it a new name and lore. Don't make a Misty Step Spitter monster look like a Phase Spider and call it a Phase Spider.
