I'm an ECU grad although I graduated many moons ago. I'm sure a lot of things have changed. I don't think recs are a huge deal however I would still go ahead and get them. Recs wouldn't hurt. Recruitment is by no means a cake walk but it's not ridiculously competitive. Generally young ladies who maximize their options can do well. It wasn't uncommon when I was there in the 90's for upperclassmen to receive bids although that could be different now.
Best of luck to your niece!
