Mezarkabul are not Opeth, nor are they a death metal act. Therefore they don't use death vox. And they certainly don't sound like a "shitty" Metallica Black-era band! They are one of the most unique bands in the world, just like Opeth. There is no other band that sounds like Mezarkabul IMO.
If you want them to turn into a death metal act, then you can wait another 10 years till some band from Turkey comes out and does some shitty death vox. It is the unique music and extraordinary vocals that differentiates Mezarkabul from all other metal bands. Turkey is not Sweden, therefore don't expect awesome death metal acts to come out of this country.
And it's interesting enough that you're using a Mezarkabul song as your screen name and bashing them all the way.
