I like Eira, I really do.
However.

Like most dragon slayers, any ice-based magic will find themselves falling short against her, since she can just eat the element and regain magic and heal wounds of all kinds.[/quote]

This is not how element consumption works. Well, not technically.
Dragon Slayers can consume their respective element to replenish their magic, yes. However, this action does NOT heal wounds.
It is the God Slayers that consume their respective element to restore health, but they can't replenish magic.

To make things clear if its not, she's been part of the guild for only a short while.

Okay, so I have to ask because it's not clear, how 'short while'? Either she's a complete newbie joining in this years tourney, or she joined in last years.
