Signature stone ideas
I know kabaam is looking at reworking how summoners can earn sig stones.  I would like to earn sig stones from duping heroes instead of just adding sig level to the champ that was just opened.   
This wouldn't really be a good thing for 6* level, unless you received 6* sig stones from duping a 5* and 4* gives 5* sig and so on.  
Just my 2 cents.  
Looking forward to most of the changes on the horizon.
