Street Brawl is fantastic. The roguelike aspect of having to make do with what you get is so refreshing. Sometimes it leads to discovering new "builds" I would not have tried otherwise.
It also got me to try heroes I hadn't yet, so I've discovered that I really enjoy Geist and Pocket.
I'm trying to get myself to play normal matches too though, because hot damn does the map look better than ever.
And vote Silver, ya'll.
