I think they are expensive! 400 cp for just 2 slots in one character its a bit too mach!! At least make them 200 cp each slot!
If i want to add one new slot to all mi characters (just one) i need to but like 1600 cp!
Slots are allready there , surely its a simple few minutes work to open more slots for players , but again we have to pay for this........... when ever my faith starts to get restored they lose it again , i can understand if it was months of extra work but this nope.
