Well it still isn't true.
With the enhancements being more front loaded now, it's much easier to get a balanced run across all elements. Sure, if you want to max an element then it'll cost more, and rightly so. But that also includes a damage enhancement to +50%, which never existed before.
So to put it in more equal terms, you have to say that it will cost 17ap to get the equivalent in one element for what you have now. That leaves 5ap left from your 22, which is enough to add +30% damage, and 4% x1.75 crit on the second.
If you wanted to be more well rounded, it is now MUCH easier to do so.
But more well rounded is the purview of Wizards. Sorcs were made to specialize.
These changes not only make sense, but allow a caster to specialize even more then before, and that's not even counting the PrE at all.
