Elise viable in 5.13?

Patch 5.13 is going to introduce some changes to some AP items and I couldn't help but think of how they may affect Elise especially with the changes coming in 5.12.

Will help with giving her tank while also giving her additional damage, especially with the increased AP on these items. Also RoA adding more Mana might help her early game Mana-hungriness. I'm also wondering about Rylai's because of this: Summoned Minions (NEW): 20% Slow for 1 second. Her Spider Minions will be annoying, that is, while they survive.

Since her healing is on Spider AAs, could building attack speed on her help more? And now it adds more AP which could be helpful.
