I'm just over the seeded booster pack thing. Played 2 pre-release tournaments. First tournament, pick Kolaghan. Go BR finish 4-1. Second tournament, Kolaghan is sold out. End up with Atarka. BR is still the best combo, scrub out. The green support cards in the seeded pack were useless. I'd rather just have a regular booster pack and figure it out from there. If some people can't have the choice that they actually want, it's probably better just not to give choices and remove the feel bads from that. And before someone comes back with the "get preregistered earlier for a better choice;" if it wasn't me getting to select what I want it would've been someone else.
I also miss the pre-release being just straight up sealed 6 packs of the upcoming set. Do I really want another pack of Fate Reforged? The fun part of the prerelease is getting to play with new cards. And lastly the prize support for the tournaments I went to was pretty weak. The undefeated players (5 rounds and 4 rounds respectively) got 8 packs and 10 packs respectively. It's worthwhile if you do that well, but it drops WAY off after that. Back when I was your age (Urza's Legacy prerelease through Onslaught), the winner of a 32 player flight (so 5-0) would get a sealed box and the top 8 would all receive significant prize as well. I know that's all on the TOs here and I've seen several other attendees talk about better prize support. I'm not sure what support Wizards gives to TOs when you have a ton of people that want to play in every tournament.
Maybe I've just become disillusioned by the whole thing. I'm already annoyed that they've gone from 1 promo to 5 to 40. I've already ducked out of going to the midnight tournament because my brain turns to goo well before the last round of that. I may be done with it altogether though and just spend the tournament entry fees on another box or something.
