The number of lesser essences required for shards of potential is ridiculously high (925 lessers for +14 potential). With the current 1 greater->5 lesser exchange, that's 185 greater conversions at 4 seconds per conversion = 740 seconds (about 12 minutes). I needed to craft three of those shards. Turbine developers: If you think 36 minutes of mindlessly clicking a button while I watched Hulu on my other computer is entertaining, it's not.
Add a conversion formula that allows you to exchange 10 greater essences for 50 lesser essences. thanks.
