Atlas Flame's power was temporary, and second origin merely put Erza closer to Laxus' level. Jura was on Laxus' level during the GMG. He would last just as long as Bluenote did against Gildarts, and Bluenote gave Gildarts a good fight. Jura and Laxus would do better than Natsu and Gray against Mard Geer if we disregard Gray's devil slaying advantage.
Speaking of Gray, he didn't even really need to close his eyes. Bixlow and Evergreen's eye magic needs to make eye contact in order to work. Gray sped behind them and then made them look at each other before they could even see Gray's body, let alone make eye contact.
Macro may or may not work on Kyria. It wasn't a huge factor during the Alvarez arc, even when it could have been super convenient. Mirajane has the chance to use it on Skullion or Madmole next chapter, so if it doesn't show then....then it's probably not going to be relevant to someone like Kyria. But like you said, Kyria is probably fast enough to land a hit and strong enough to do enough damage to take Seilah out if the hit lands.
