My response shall feel slightly off-topic but although it's always nice to have drop tabled updated like you suggested, the recent drop in blood runes since the Runecraft updates have basically halved the GE price of them from where they were.
I'm certainly not against it but I do wonder given that market whether it's still a good idea to increase the supply of them further.
Thanks for the feed back on this topic. I took into consideration all the above before thinking about even posting about this concern. I hope someone down the line might want to implement more frequently dropped runes. However, even consider the drop be expanded from at least 30 to more at a time would be a nice addition considering the drop rate.
