"In addition, packs that you open during a Draft event (see below) will count towards your Vault progress. " This is wrong, they clarified on the beta forums. Chris mispoke on the stream that people are getting that tidbit from, we are guessing it WAS that way and got changed late in the development cycle and he forgot. The packs you open to pick from will not count, but the ones you get from prize support are normal packs that always do.
This update looks ok on the surface, but all the ways they added gold or 'value' they took it away somewhere else, basically. Packs were over 4% of vault progress before, now 3.3%. Individual card rewards (ICR) were removed (which is fine, no one liked them) for the extra daily gold. That's still a better deal, increases player agency by letting them pick the set and increased chance for wildcards, but we aren't getting 'more' overall. Also, the vault is 1 mythic WC, 2 rare WC and 3 uncommon WCs now, which is better, but still not good enough for how rarely you open it. Also, they reduced the 'pity timer' rates on wildcards in packs, so you can go longer without opening a certain WC.
The constructed events look like the way good players will really go 'infinite'. 4 wins gets you your entry fee back +some ICR. Not too hard to average over 4 wins for good players.
However, the draft reward structure is silly. You need to average 5.5 wins out of 7 to go 'infinite', and literally your number of packs for reward are randomized no matter how many wins you get. 1 win? Oh you highrolled into 3 packs! Hurrah for you this time! 7 wins? Nice job! Here's 1 pack, thanks. Like, wtf? 5 wins should reward your entry fee worth of gems back, and the pack rewards should scale. ex: 1 pack for 1-3 wins, 2 for 4-6 and 3 packs for 7. I mean, even hearthstone figured this shit out, and they are stingy as hell. 7 wins out of 12 is 'infinite' in HS arena and that's certainly easier then 5.5 out of 7.
His logic for the events serving different purposes is fine, but then they got the reward structures reversed. Constructed ones are always available, and is supposed to be a way for hardcore players to 'keep playing arena'. Draft is supposed to be an approachable way to learn draft but then you have to get 6+ wins to be able to afford another draft, lol. Needs to be an easier way for a player to get back to a draft if they did 'ok', but maybe had a bad deck or a couple mistakes in draft picks. As it stands, they won't be able to get more practice at it for awhile, unless they just buy a ton of gems.
On the positive side: Their pricing seems fair. Was afraid they were gonna do something stupid like $2+ per pack or $10+ for a draft (some leaked info early on suggested drafts were originally planned to be 8-10k gold, so basically double these prices). Can buy packs for close to $1/each if you buy $100 worth of gems, which is fair enough. In an ideal world, they would have been $1 to start, and as low as $.75 if you bought in bulk, but that was never gonna happen with the greedy bean counters at hasbro who can't see long term enough.
