For 500-750 crowns you can buy a pack based on a year of bundles, and get pets, wands, mounts, armor.... Everything from that Bundle except the house...
For example... 2010 bundle pack would contain items from Epic, Super, Mega bundles... Etc... 2017 would have fantasy voyage, mirage, Avalon, etc....
All the items are already leveled based, it's probably 5-7 bundles per year.... I'm pretty sure even with it being 500-750 crowns... To a actual bundles 40$ .... It'll balance out.... You can either gamble and buy a million packs till you get the full bundle.... Or wait 5-6 months for KI to put it online and buy it whole..... Have it every month... They exchange the 3 bundle pack years....
