Feel free to do what you like, but I would recommend that you consider quality over quantity, having lots of half-finished arenas is not anywhere as good as having a few very good ones
david: Nothing to be sorry about - addons are there for people to get their work out even if the quality isn't too good. It was merely a suggestion from Auria's side that you might want to try spending more time on each arena, such that quality might get better. But that's entirely up to you.
Hey pal, I took an oath for justice! "In happy days or tightest tights..." or something like that.
