The no add subscription is far more fair priced. Tbh the automated incasso however is a bit clever to obtain a steady cashflow. Yet the lack of a temporary no-add addition to diamond purchases and the addition of payed event passes might negatively impact diamond sales, I fear.
I would like to friendly suggest the following;
Diamond purchases - 1 add free day / €5 spend
Diamond purchases of €50 or more 1 event pass token*
This way diamond purchases might become more appealing again. As for example a package of €60 (through the app) would give under normal conditions:
Diamonds
30d no adds
1 event pass of choice
Which would be a solid deal for those who like to support the game financially and wanting more diamonds.
Further more Inno could subtlety combat diamond farming by the following subtle changes:
Annual caps on diamonds obtained from:
WW/FoY (e.g. 1/month - 600-1.200d annually, unboosted by bg/boosted by bg)
GbG (eg 60/month - 720d annually)
GE (100/w - up to 5.200d annually)
Total annual cap: 7.120d
Those changes can be subtle and will only affect renewable diamond sources. The changes should be an any world cap for each player individually. As diamonds are shared on an account by all the worlds. An more complex alternative has also been suggested often:
Free diamonds not to be shared by all worlds of a player, while purchased diamond would. The issue however is that it'll cause confusion due to each world having a different number of diamonds. With the previously mentioned subtle change, it's hardly noticeable beyond a cut in diamond production from renewable sources.
Overall my suggestions are just aimed to improve the deal diamond sales offer. As otherwise it might become very appealing to Inno to locking much more diamond features behind paywalls. Like it was done with the event pass. By restricting renewable diamonds to a reasonable high annual amount and making diamond purchases more appealing, diamond sales might become more appealing.
While the ads free subscription will remain a better deal. As it's just €5 vs €60 for a month. Even if some feel the €60+ deal is better, it's for each of those players that going through with that an additional €55 for Inno in that month. So, the house wins always.
*the token allows a player to unlock the event pass without spending extra money
