Allagast Mage Hunters shit all over Blademasters in just about everything. Unless it’s a broken Shattered/Reaver Claw BM it’s not even close. Spanks’ version is indeed on the squishier side, but he just likes to play them this way.
You can take @Dmt’s Mage Hunter, she builds caster-tanks that smash deep shards.
It’s been a caster’s meta since forever.
