Both of these abilities in their current state are pretty underwhelming. With the removal of Pageflight's damage bonus, you get a barely noticeable buff with some minor survivability components. Wordwarden is in an even worse place. Even with Noctua modded out for max damage (which also defeats the point of it's unique trait of multiple tome mods), it still isn't doing enough damage to feel worth casting.
Here's what I think could make these feel way better.
Pageflight: Return some of the status damage increase. I think it'd be completely fair to have this reduced from how Dante launched since that did seem a bit crazy at times. However, instead of removing it completely, add it back in at maybe 50% of what it was at launch.
Wordwarden: Allow the Wordwarden tome to cast heavy attacks so it can activate tome mods. Have it do so at a reduced efficacy though so that there is still a reason to summon Noctua manually and attack with it. For example, instead of getting 10 energy per second at max stacks of Xata Invocation, maybe you only get half at 5 energy per second. Or maybe it's only 20-30% effective, but also benefits your teammates. Being able to share your Noctua mods with your team would be a great way to reinforce Dante as a support frame.
I do appreciate the speed at which the nerf adjustments were addressed, and I hope these suggestions are helpful to the cause of helping Dante find his role.
