Just an observation about the booster packs, pack II has 5 times as many whips as pack I but still has only 1 gem pack.
This makes pack II over 200 balens more expensive than 5 x pack I not to mention the fact you're potentially getting less gems with pack II than you would with 5 pack Is
Also, a mount training whip is 35 balens each, pack II has 50 which, if bought separately would cost 1750 balens (149 balens cheaper than the pack). Yes you're getting a lvl 3 gem guaranteed extra but not much discounted price to mystery shopin comparison with the discount that pack I affords.
Buying 5 x pack Is is also cheaper than buying 50 individual whips (don't forget the bonus gem packs u get on top with pack Is).
tldr - pack I is definitely value for money if you are considering buying whips, pack II is not. buying multiples of pack Is is probably preferable to buying 1 pack II.
