TheVaultDweller
Front line cannon fodder
Not sure about how he does against everyone, but I would just like to point out that I feel some people are underselling those shields. He initially had trouble with them, and they weren't very big to start with, but his shields/defense is one area where he improved in the most, across the film, IMO. When he faced off against Dormammu, at the end, he was able to raise them very quickly, they were each about the size of Cap's shield (he was able to put nearly his whole body behind one when he blocked the one beam), and managed to hold out against previously mentioned beam for a good few seconds before giving out. And when the beam actually hit, it was powerful enough to pretty much atomize him (so it shows they can block a pretty decent hit).
They even still had a shot of it in the one trailer (by the end, they were much larger than dinner plates):
So his shields + cape makes defense one of his better areas.
