My only issue with this update is the cost disparity for low level elemental runes in the shop.
100 Mind Runes = 700 GP
100 Mind Runes in a Pack = 10,000 GP
100 Air Runes = 800 GP
100 Air Runes in a Pack = 10,000 GP
100 Water Runes = 800 GP
100 Water Runes in a Pack = 10,000 GP
etc
I'm guessing this was done to prevent splashing but in reality its just excessive, you're completely forgetting about new Iron men who won't be able to afford any of the new packs due to the extreme price gouging and if the shop isn't meant for them then why even allow Iron Men to buy from it in the first place.
And since all the runes are super low price in comparison to the packs it results in 1 person buying out the whole shop for no more than 200,000 gold (And thats including Mind Runes, and why not throw in another 70k gold for the 5000 Body Runes even though they are useless.)
5000 x Air Runes = 40K,
5000 x Water Runes = 40K,
5000 x Earth Runes = 40K,
5000 x Fire Runes = 40K,
5000 x Mind Runes = 35K,
Total: 195K Coins to fully wipe the shop, or 265K including the Body runes if you wanna be a bit cheeky.
Its absolutely crazy. The two best options would be to
1) Increase the price of elemental runes across the board to try deter people buying out the whole shop for literally less than 200k gold.
OR
2) Lower the price of packs and increase the amount in the shop.
OR
3) Add a snowball effect to the cost like in normal OSRS to prevent people ripping the whole shop.
