Welcome to the forums. We love to have new players in the game. And make sure to get your friends involved. More play time will make you a better player over time.
I got timed out and lost my lengthy response to the errata question. As a note to the moderator, why do we get timed out when we are actively doing something on the site? It seems that only IDLE connections should start some timeout clock. And that any keyboard activity should reset said timeout clock.
The reason I am opposed to errata is that I really hate that I paid money for something that is printed, and I have to check some external source to see if it really is as it is printed. It means that the company that printed it couldn't be bothered to get it right the first time, just winged it and printed anyway. It means that consumers are beta testers. New players can get very easily confused that their play is incorrect, because they did not keep up with some website. I hated it from wotc in mtg. Cards outright banned even. Really? I understand things cannot be 100% 100% of the time. But for something this mature (multiple years in development) and within 2 tournaments, they had to errata several cards. Some of that should have been caught. And folks here are clamoring for even more. If you want to change mages, then change the necro poison immunity. But I am not advocating errata for the necro, just pointing out something that is so much more egregious than the wizard base stats.
Errata is a very last resort. It is expensive for the company to reprint cards. It is expensive because of the hit to confidence in the company from consumers. It implies they do not do enough testing before printing. It should be extremely rare, and very considered when implemented. Something that is lost in the din sometimes.
