Gothic fonts usually don't translate well when they're used in
all caps much like script-y fonts. They should've kept the ARENA TOUR 2010 in Impact and had the subtitle done in the Gothic font.
Again, I don't know why CDL09-10's logo was so unreadable for some people... the letters were clear for the most part, it's just that the C, D, and E were huge. It takes a second to figure out what it says, but it is far from illegible imo.
