With this and the spellsword class, I think we're seeing a definite power creep, and it's one that's already starting very early on.
The Swordmage deals the lowest damage of -any- class out there I would wager right now, and one of its build options (Assault swordmage) is pretty suboptimal for its designated Defender role. It has a lot of tricks and mobility, is fantastic at AoEing and clearing out minions (A trait it shares with the Barbarian) and its defense orientated mark (aegis of shielding) is rather good, but I don't think it outpaces either the Fighter or the Paladin in the stickiness department, and it certainly has nowhere near the capacity for damage the Fighter does.
Barbarians, due to chainmail, start off inherently with one less feat![]()
Technically, so did Druids in 3.5 because they had to take Natural Spell. ;P
