No, davey, this is what you said
If you cant play metal in A-440 you shouldnt be allowed to play guitar
no you dont need your guitar in Drop-Z ... just learn to play properly. and no, i dont buy the 'it sounds more brutal' or whatever point you're trying to make
THE END
And it doesnt say anything about you being annoyed that people dont set their guitars up for detuning. Its being annoyed at detuning in general. "If you cant play metal in A-440 you shouldnt be allowed to play guitar" suggests a limited view of what is and isnt metal. You really CANT play some of it, actually, a lot of it, in standard or drop D. it would sound as gay if you did as playing detuned with 10s sounds muddy.
