I've been a Destiny fan for a long time. However, I've had a couple issues with the game:
1) Phasing out Awakenings, SOR, and EAW. I spent a lot of money on the first 3 sets, before FFG made the Holocron announcements. I'm fine with the Infinity, Standard, and Trilogy formats. However, I'm a little upset that my old cards are useless, and there's not too many Infinity tournaments in my area. How about if FFG makes a format where they pick which sets/blocks we can use from all sets released so far? At least our old cards wouldn't be totally useless.
2) I can't tell you how many friends I've introduced this game too where they buy cards/start sets, only to find out cards have been errata'd after the first game. The sheer frustration alone on this one thing has been enough to keep most of my friends from being fully committed to to this game after making what they think are awesome decks. I'm not sure what the solution is, but I like what AEG does which is to insert updated errata'd cards in the next sets. Or maybe at the very least make them as tournament promo cards or something.
Would love to hear your thoughts.
