LONG VERSION:

She's a sheltered nun who has had to behave as a saint never asking for anything ,never being shelfish, never desire anything , like a machine.

I'm certain her first time acting as a normal girl was the first time she met Issei and they went on a "date".

Just like issei who had to take steps in becoming used to girls she had to take baby steps into acting like a normal girl.

You call her stale because you've gotten used to extreme behaviour paterns anime/manga/etc have gotten used to using for girls.

She's a mix of light tsundere/ pile of kindness mixed with lots of adorableness with some jealousy/possesiveness towards Issei but everything is in light amounts so it's not too noticable.

And onto you asking her to step up and get new powers.

1. she wouldn't hurt even a fly so attack powers are out of the question.

2. defensive she has Fafnir and several evil dragons if something can get through fafnir that means any defensive powers she would need to develop would have to be dragon king tier which would put her defensive skills above Rossweisse which would lower Ross's worth and disrupt the balance the gremory team has at the moment.

(and it would also make her move further into the front lines which is stupid to do with a support/healer character)

So no that doesn't work support wise she's already at top tier being able to heal mortal wounds so adding unto that would be overkill this already makes her the most IMPORTANT character in the team.

The gremory team already knows this and that's why she's in the back protected by everyone and because she's in the back ready to save them from mortal danger everyone in the front can fight even harder that's how it works.

So as you can see NOT dead weight you're just too fixated on the idea that everyone has to fight and have flashy abilities that's not how a support type works.

SHORT VERSION:

She's the kind lovable slight tsundere type girl who's just started behaving as a normal girl thanks to Issei and just like him she'll be taking baby steps to develop herself even further as a girl/ dragon tamer/ healer who's not supposed to be on the front lines or HAS to cover all her bases or having to be perfect.

The whole gremory team has flaws but they work as a team and that's what it's all about and it's also what makes them human and interesting.
