I'd like the option to choose what colour scheme my figures are using. Some of the options are great but only accessible if you play 2 or 3 of that class. I don't know if I'm alone on this, but I find the chat notification when an observer joins quite annoying, as you can't differentiate between that and your opponent chatting. Surely collusion isn't so rife that an alert is required? By all means have it feedback to chat, but I don't think it should show up as a new message.
Both are good suggestions. See earlier discussuion: http://forums.cardhunter.com/threads/suggestion-player-selectable-character-color.7820/ & http://forums.cardhunter.com/threads/suggestion-alert-on-spectator-joining.3302/
As a new player, I agree with both suggestions. I just noticed the alternate colours in a quick draw match today, and I immediately thought that it would be great to have them selectable!
