I feel like it needs some work.

I've been in beta for 3 weeks now, and there are two GUI elements that still aren't that intuitive to me. They were very frustrating to use when I first started, and are barriers to newer players in my opinion (and even my friends that are DotA veterans)

1) The gold indicator is really hard to see (this already has another thread though)

2) The exp bar is really small and doesn't stand out very much

I believe both of the elements suffer from the fact that a light colored text is used on a light colored background. This is also compounded by the fact that the text size is fairly small. For the exp bar, this goes for both the level number and the amount of exp. I also feel that the exp bar is extremely tiny when compared to the DotA 1 exp bar.
