Ignoring the goofy profile pic they gave him, Asuna is underrated. People will spam threads talking about how he'll mess up a satchel, and then ignore the multiple rounds he cleared the entire site by himself.
I'm convinced the only reason is because he avoids flashy kills, so he's overshadowed by cryo or bang. But between all the members of 100t, I'd take Boostio and then Asuna in that order.
