They never show everything that's been added in the patch notes.
The AST changes displease me on a conceptual level. Lightspeed was made all the more into an MP cooldown rather than an emergency heal. They want us to use it which is why they removed the damage debuff but I really wish they had gone another route with this instead. Not to mention that it's still only MP cost reduction, we'll see how much it'll help instead of another source of active MP refresh. It feels like they're sacrificing AST utility just to keep them with mana (Lightspeed, Celestial Opposition used to prolong your Ewer and Lucid Dreaming). Oh well, we'll see how it plays. Lining up the cast time to give room for cards sounds nice.
Aspected Helios cast time reduction is a welcome change, though.
