Choosing a new character

I have had a bit of a problem desiding on my last character to main. In my opinion you should have 2 characters in each of 2 roles and I'm a support and jungle main who currently plays lulu and Soraka support and Ivern and Gragus jungle. My main problem is Gragus doesn't really fit my play style. I like saying my team is never going to die even if they're a brain dead and 0/10 so support was an obvious choice and Ivern is fun and fits my play style but I just don't like gragus. I thought about Galio but I really don't know and I thought I would ask here before I spent the IP on him. They don't have to be top percentage OP challenger jungles but I don't want a trash or MEME champ either, any suggestions are welcomed.
