Personally, I dislike the event system. The same players win the same events over and over. By doing so, all the other players get shut out from earning their event coins. Take someone like Paul Frank for example, he was (and maybe still is) amazing at events, and he continuously wins them. How can you expect someone new to defeat a players who's been doing the same thing for months?
I think we need a new type of currency that is available for all players.
