These are exactly the changes I said they should make (though I'm not posting on the JP forums so I doubt they got the idea from me).
Basically, I had been saying that they need to make the AST 90% as effective, healing wise, as SCH and WHM and let the RNG of the cards make up for the last 10%, and I think we're at that point now.
Given that healers are the largest determining factor in raid progression (ie if a healer is more powerful than they should be, then they can potentially allow raid teams to survive mechanics that they don't have the gear to be surviving yet), I'm not upset with Yoshi-P in the least for the fact that ASTs had to sit out these savage world firsts. In hindsight, it was inevitable. Yoshi-P erred on the side of caution because he wanted world firsts to actually be a big deal instead of a faceroll that happened week 1, and believe me, we should ALL respect that decision.
World firsts in FFXIV SHOULD be a big deal, and that's not going to be the case if it happens week 1. If we can get sponsored progression raid guilds to start coming to FFXIV, it'll be AMAZING for the game's overall popularity. This is the real reason I created a thread for this (I meant to do it the other day): don't blame Yoshi-P for this. There have been many cases in the past where MMOs released a new class too powerful (Death Knights) and it was a huge debacle. He made the absolute right decision for doing it this way.
Now, on the subject of the one place AST is still relatively weak: mana regen.
With generally-improved healing potency, we'll hopefully be going OoM less often, but it's still possible to go OoM if a situation turns sour or if you're just trying to heal a party who is bad at not standing in the bad.
In that area, we're still going to be leaning on RNG to help us recover MP. In essence, we ARE still a luck-based class, especially since Spear wasn't buffed and remains a pretty awful draw (RRed on sight...).
Overall, it feels like a good place for the class. We'll see if their representation increases in Savage teams now...
