Nope, it's fine as it is, it doesn't need re-inventing. Cards also don't need another buff when they can be royal-roaded as you please. Astro is already unique as it is... Not saying "git gud", but after some practice I prefer it now to my WHM which I've played ever since v1. Of course it will need some twerking here and there, just like all jobs when more content comes and more play styles are added. But as it is now, it's ok. Don't try to change it into something different.
