Pretty much the title. We get a lot of messages about how we should bring the Feral Druid, rather than just a Druid, that specs should feel distinct enough that you feel 'your guy' is a Demonology Warlock rather than just a Warlock. That specs should be close enough under most circumstances that you don't feel compelled to swap spec, but have strengths to shine occasionally. It's the fall back argument against Tri-Spec and for differing gear sets per-role and spec. It's even been suggested more than once that Dual Spec itself fixes a problem that no longer exists thanks to tanking and healing changes that make them pretty viable for questing.
However, with the new gearing system the objective seems to be to make it easier than ever before to swap specs and roles, removing the barrier to encourage a focus on a spec or role so your guy is more than just 'A Paladin'. It seems to fly in the face of all that discussion that's gone before.
I still feel like a specialisation should be a commitment; barriers need to exist to allow players to focus rather than feel an expectation of knowing all of the specs. It is afterall, an RPG where your choices in specialisation and talents are supposed to reflect something within your character's character, something that defines them. Too much ease and convenience hurts that, and we've seen countless arguments on how ease and convenience hurt immersion and gameplay itself.
