Second-tier bands are often labeled so due to their lack of innovation. Why shouldn't a genre be labeled accordingly?
Second-tier means lack of innovation? I never knew that. I've never personally given that much weight to innovation in metal so maybe that's why I didn't know it meant that.
Doom metal was never meant to be much more than Sabbathian worship so it's not really worth debating, they wear their influences more on their sleeves than black metal most of the time, though doom metal has perhaps accidentally spawned many cool bands with distinct sounds. Scald comes to mind.
