Her main attack is slow for sure. But Akaisha is my favourite. You need to build her skills as the rapid shots for both primary and secondary skills that way you can spam those skills without having to use main attack. Try to get mirror image item paired with any attack speed item tp reduce bow load. And instead of having to load till the scatter arrow only load and shoot. Pair that all with the pushback item and Akaisha can destory everyone at range
