Is this really healthy for endgame gorup composition? I mean we had sorcerers used as healers for more synergies provided, so it is a mechanic that enforces having different classes for sets that function based on synergy.
With the implementation of necro and avid boneyard, necro tanks can have pretty much 100% uptime on alkosh with just shards and themselves, necro mag dps can have reliable moondancer uptime and stam necro can have insane uptimes on major slayer with lokkestiiz.
IMO this moprh should provide something else, the whole concept of synergy is to have the group work on helping each other and having different classes present, this will further increase pve class stacking.
