First of all you don’t need to prove anything to anyone. A few people on the internet disagreed with your own opinion about a video game, it happens, a lot in fact.
Second if a build works for you, that’s great, it doesn’t have to be “meta”, it doesn’t have to clear in record time, it doesn’t even have to be efficient, if it works that’s all that matters.
Third I believe the argument here is that blue glyphs can work, and I’m fairly certain the argument against it wasn’t the fact they can’t work, they just weren’t as good as yellow glyphs. I dare say you can even argue that no glyphs will work, I’ve yet to see anyone try higher tier’d NM’s without glyphs, but I have no doubt people could make it work. If you didn’t waste the paragon points on not only getting to the blank glyph spots and filling in the necessary requirements for them, you could focus on getting the rare and legendary tiles much faster.
Trust me when I say you have nothing to prove, your build works for you, that’s all that matters regardless of what the naysayers say.
