I´m pretty much ok with the sell fee and the resource cap. I believe without either of them there would be a room for breaking the system. But I do miss the trading part of the event, I had a lot of fun with that last year regardless the extensive rewards.
In my opinion the whole problem is that the prices never change more than +/- 1 coin per piece. Also I´m curious how the price is calculated, because it remains practically the same on average. I would think resources would be more bought and less sold, since they are eventually spent, therefore price should gradually increase during the event.
I would very much welcome, if the event would reward either cooperation with other players or a bit of smart thinking. Maybe cap the price change on +/- 3, which would mean max. 500 coins per hour profit. And make the price change depend on the number on players participating in the event. Something like 5% players trading = +/-1 coin.
Example based on my server:
- about 600 players in event (that have some diamonds)
- 5% = 30 people = 3000 resources traded (of 1 kind)
- if 15% players were trading every hour every day and with all resources, that means 8 days * 24 hours * (3 profit - 1 sell fee) * 500 resources/2 (buy first hour, sell the other) coins = 96000 coins = about 640 runs = about 2,5k diamonds
- but it costs about 8,5k coins to get 100 pieces of every resource, therefore the actual maximum number would be a lot less
This might be a bit too much straight forward, but it might be fun to see the whole server work together.
