Here's the thing Misk, it's been heavily implied that Irene is going to be a witch from her looks and magic (so yes, it's about the looks in this case because it adds credibility to a backstory; looking at Brandish and her relationship with Aquarius aka "servant-master" relationship), but then the whole "Dragon" subplot happened and that basically caused much outrage in the community for many reasons, some of which I explained above.

It would've made sense and helped made her backstory easier to swallow. It's not really random, but something that's rather critical in a sense because of people getting a feel for another going by looks alone. I mean, if you saw Erza wearing knight armor, you automatically assume her magic is something related to it; but then, from out of nowhere, she uses Healing Magic for lord knows what reason saying she's a supportive mage, having no offensive or defensive powers to speak of.
