It seems to me that the advantages offered by the Greasemonkey Conquer Club script mean that you'd be at a significant disadvantage playing without it.
I've started the poll as I'm curious to find out if anyone is actually playing without it ...
The "number of cards held" statistic on it's own makes the script really valuable. Short of scanning the game log and manually calculating how many cards each player has, this statistic would be all but impossible to keep tabs on otherwise especially when playing multiple games.
Perhaps I should start a new topic, but I'll ask here anyway - does anyone know if there are any plans to add some of the functionality of the Greasemonkey script to the core code of the site? Perhaps so that newbies aren't at an automatic disadvantage until they discover the script?
