A4S Solo?

So I've just recently stumbled upon the idea that early savage content is soloable for mount farming and such, and upon looking further, I discovered the difficult task of meeting a burst damage requirement for getting the last leg down in A4S. I'm a lvl 90 GNB. Would it be possible for me to do this solo? If so, what moves/strategies should I be prioritizing? If not, what's the complete list of classes that are able to solo?
