-WCannibal made me lol.
Technically I think Ancient is right, Deathcore has become more "brutal" as in it has become more extreme. Faster tempos, more extreme vocals, shit like that. Alot of it is just production, Ancient has never seen a real death metal band live. On whole though deathcore is not better than death metal. The only band I've personally thought made as good of riffs as Morbid Angel was TBDM only because they're really catchy. Some deathcore bands occasionally make a really good song, but mostly they're quite mediocre. They aren't bad, but being original would help a lot of them sound better, instead they follow the lame breakdown/technical/breakdown/solo/breakdown/technical/more breakdown formula for their songs. This might make more noise than some deathmetal bands, but they are not more "brutal".
There are bands like "I declare war" and "disfiguring the goddess" which makes brutal as fuck music even if it's deathcore, but they are barely deathcore. They use breakdowns like they're meant to be used, as a technique of guitar not the sole purpose of the guitar.
All in all Ancient is right in his own way, deathcore is more extreme, but not more brutal than death metal.
ps The more you talk about him being a troll the more he's going to do shit like this. Don't pay attention to the troll and it will go away.
