Gaara is still squishy in a front position, even more noticeable due to wind mains lack of consistent sustain. The issue is in part based on the age of your server, since it much harder to run buff heavy teams once Han and 5kMadara start becoming more common. Kurenai is valuable here since she has the sustain that wind main lacks by default, allowing for you to get more out of the team. Plus the chaos added from her skill books.
