^ price adjustment on Resource Packs making them all worth the same value is a start.
And a Cool down / Reduction of value for repetitive purchases, ensuring that players who purchase the 1 Pack wont be Penalized compared to a Whale who purchases 100 in a day.
(although only for merchant packs, not the Free Resource packs we get occasionally from rewards)
one way is to Limit Exactly what is included into Resource Packs past the First daily Pack. Such as to only include be 100% of Base mine Production, +25% of all other Boosts.
this is one way, that i can see GF opening up the game to allow Active Players to Benefit from things such as Crawler Cap Being Removed,
only able to purchase DM in the Server Local Currency, and server transfers to have purchased DM Ratio's to match the local currency.
Reduction In resource Production Boosts Price (10%,20%,30%,40%), to encourage Active Players who Rarely Use Vac mode to Invest,
just my 2 Cents, not every Suggestion Will please every player. but resource packs need to be Nerfed for Those who Spam them. and Balanced Because of how Metal Is usually 3x your Duet Production, but 1/3rd the cost instead it should be the same for each resource @ 126,000DM ( or some middle Ground Value)
You're still suggesting that ress packs or DM need to be changed but the problem lies much deeper than that. In many other "p2w" games - I'll use Genshin Impact as an example - whales don't receive the amount of backlash that they do in ogame and they certainly don't "ruin" the game.
Take a step back and think of the reason for this, and you'll be able to come up with suggestions that actually have a chance of being considered.
