Q: How will artifact weapons be handled for specs that use different weapon setups? (ie Titans Grip vs Single-Minded Fury, Dual-Wield vs 2h Frost).
A: Ion Hazzikostas: The kind of plan there is that there is one specific artifact per spec, so, using Frost Death-Knight as an example: Currently they can pick a single two-hander or they can dual wield. The artifact, is going to be two one-handed runeblades, so, that spec is going to be much more focused on dual wielding and Frost will be the Dual-wield spec in Legion and likely beyond, whereas Unholy will continue to use the two-handed Runeblade.
A: Ion Hazzikostas: In the timeframe of Legion, the Artifact will be pretty much the only weapon that you wield.
