I was about to post the same thing, phew..
So I'm thinking about different ways to fix the 'my cards' system.
About the 1st of your points :
-New accounts start with no gold and they need to meet played games/amount of time requirements to be able to start "collecting".
-New accounts start with a sealed pool of unsellable/unsellable cards precon + boosters and NO gold.
In general I strongly believe new accounts shoudn't be allowed to be involved in the game economy from the start.
2: Allow the merchant to sell packs, but not singles.
This will make the dailies very luck dependent and near unplayable for some people. It is strictly worse than a sealed tournament.
3: This can partially solve the problem, however there will be a lot of arguing involved and many unhappy people (including me). Maybe the best decision from these 4...
4: No idea how was the merchant before that....
So this is my idea: I do believe that the new accounts shoudn't be starting with any gold and receive it only when special circumstances are being met. Also no gold at the beginning of the week, some packs and league/tournament "ticket" for example instead. That involves the merchant selling more tickets for people who can afford to pay for them. It is kinda the same thing as it is right now, but less currency involved and more not-so exploitable stock.
This will allow new players to join tournaments with their tickets, from where they can expand their collection. They can still get lucky and open some good cards from their starter set or monday wage. Also I suggest some gold award at dailies and other tournaments and completely remove any other way to get gold besides selling cards and tournament wins.
Offtopic: There were some friendly comments about my collection since the reset- I would like to share how I've done it: At first - I was one of the few people who joined the site after the restart, so I've spend 120 gold on 6 top-quality rares. Then I bought 1 precon (Sam's starter from
mount doom) and sold everything besides 2 Sams(I knew I was going to buy one more starter, since I need 4 Sam for my deck). I finished with like 10 gold ahead after doing this and reported it to MarcinS, asap. We realized it can't be done more than once with each card from the starters since the prizes were reduced drastically, so I bought another Sam starter, One gandalf starter and one Boromir, finishing selling near everything from those decks, leaving me with the cards I needed and 1 site path for each format. That left me with some more gold to spare, which I invested in good rares. After midnight before the late daily I received 50 gold more to buy
Legolas, DH and stuff for my movie deck. I finshed 1st on the daily - 10 boosters. Won 2 or 3 more from the ongoing limited league. The next day I won the fellowship daily getting 10 more boosters. So I guess I was lucky to be from the first ones who joined the site and spent their time thinking for the best way to start the new "season".
