This is really interesting, since we are now in an area where I really do pay attention and do care. It looks like we have categories of spells (summons) that are being entirely reworked mechanically and some minor tweaks, but not much else?
Maybe I will be beaten up for this, but not addressing the Shield spell (which it truly seems they have not) is a big deal. It's one of the most controversial spells on the Wizard side of the aisle. I will absolutely not complain if it stays the same.
I wonder how Spirit Guardians is going to interact with the change to summons. If I understand, summon spells now have an aura where you cause damage, which is sort of Spirit Guardians thing.
I find it interesting that not a lot has been updated or changed in this area. And I'm kind of surprised how that works out, considering what happened to classes. This is going to be an exciting August 1, since that's when the embargo on discussing changes ends.
