It would be nice to be able to sell souls. Right now we are stuck with converting souls when our slots are full even if we dont want or need any toons. With all the new souls added they need to increase the available slots. Now they make us spend our gold just to keep playing filling our roster slots up before the next sac event occurs or sacking them even if it causes a vortex to trigger.
What a new predicament this is becoming. Same thing with shards and runes, they keep adding new ones while the slots remain the same. Now some of us have to sell resources just to be able to play.
