So... I don't mean to be rude, but I really can't comprehend why fixes/updates to the online card database and spell book builder take so long. It seems like it should just be a matter of adding entries to an existing data base. Seems like an hour or two of work for someone familiar with the code, assuming the data base code itself remains unchanged (just adding more entries).
Domination has been in the wild for about 6 months, and while cards have been added, there are still bugs that prevent some of them from being added to spell books - most notably that you can't select Domination as a product you own (it isn't listed under Spell Books Sets), and even if you click "Ignore Spell Counts" you still can't select some cards (like Galaxxus) using some browsers because they have the property Mage Type = Epic.
Second, Academy has also been available since Gen Con and has been available retail in many countries for at least a month, and Academy cards aren't listed at all yet. I think that should be a high priority given that Academy is getting mostly good reviews and could bring a lot of new players to Mage Wars - but it would be a LOT better if the format was supported in the spell book builder ... not to mention that it would allow Arena/Domination players a convenient way to build spell books with Academy cards without painstakingly adding up spell book points manually. You definitely want to get support for Academy before the "new shiny" appeal of Academy wears off...
Third, some updated card text, art, etc for 4th printing core and expansions (namely FvW) isn't reflected in the builder. For instance, Goblin Builder doesn't have the new text allowing him to repair walls... although I did just notice that Hand of Bim-Shallah, Battle Fury, Temple of Light, etc, have been updated with the new art/text versions; and Skeletal Sentry is now a soldier, Malacoda is now poison immune and deals poison damage, etc.
Fourth, and this is more selfish and a little off topic, but it would be nice if Academy were available in the Ambassador Rewards section of the Arcane Wonders online store. Despite my personal misgivings about Academy (and overall preference for Arena/Domination), it is a great tool for introducing new players to Mage Wars, which is really what the Ambassador Program is all about.
